The poem you refer to is called "Songs of Sorrow" by Kofi Awoonor. Kofi Awoonor (1935–2013) was born George Awoonor-Williams in Wheta, Ghana. Besides being a poet, literary critic, and professor of comparative literature, he acted as an ambassador for Ghana.
The first stanza of the poem reads:
Dzogbese Lisa has treated me thus
It has led me among the sharps of the forest
Returning is not possible
And going forward is a great difficulty
The affairs of this world are like the chameleon feces
Into which I have stepped
When I clean it cannot go.
