What does building the compiler exactly means how does this differs from installing the compiler in perspective of GCC?

Installing a compiler, not just the gcc compiler, is a process where you copy the various executable files to the installation directory, where you copy the various header files to the include directory, where you copy the various library files to the lib directory, in short, where you install the compiler program and configure it so that it can do its work, namely to compile programs. This is no different than installing any other program, such as the game Myst. Building a compiler, on the other hand, is the process where you use a compiler, or other tools, to compile a set of programs that represents the compiler. If this sounds circular, consider this... The game Myst is a program. You install it in order to play it. When you run it, you load and run the executable code that represents Myst. It also has source code, though you probably can not get a copy of that source code. You build Myst by compiling the source code into object code, and then linking an executable from that object code. Building a compiler is no different. It is a program. It has source code. You build it by compiling the source code into object code, and then linking an executable from that object code. When you do this to a compiler, however, you need to distinguish between the compiler that you are building and the compiler that you are using to build the compiler. Sometimes, the compiler is used to compile a new version of itself, in a different directory. Sometimes, a different compiler is used, such as using a simplified version of C to compile a C++ compiler.

It is also important to note that the process of installing a Patch differs from the process of installing a Service Pack.

Where does PHP differ from other computer programs?
First, let's make this clear: PHP isn't a computer program; it's a programming language that has a JIT compiler (the program named php.exe), but when taking about php you usually refer to the language and not the compiler exe from the language. It differs from other "normal programs" (for example: firefox, audacity, your games, etc...) because it's a compiler: it inputs data (usually a text file) and output a exe, the program, that does what the input file told the exe to do. PHP is most used in web cgi and it was it's original purpose (dynamic server-side pages), but is enabled for tools such as Windows Scripting Tool.
What is An etic perspective of kula exchange?
From an etic perspective, this type of economic distribution provides a method of shifting products from regions of plenty to regions of scarcity. As Harris (1987) notes, the etic perspective of the kula differs from the emic perspective described above. The kula ring is ceremonial in nature and not a barter system. However, kula voyages can promote utilitarian trading. Men on a kula expedition carry both food and manufactured items, including pottery, baskets, and mats, to places lacking resources and trade for materials to bring back to their villages.
