You almost certainly have multiple versions of GTK+ installed
in different places on your system, and the compilation
is finding some of one, some of another. 

(The automake macros that come with GTK+ will actually
 detect this problem if used to build a program, but it
 doesn't sound like the program you are trying to build
 is using them.)
