I've seen this occasionally. If you check gtk2hs-confg.h near the bottom of the file you'll likely find something like

It is ./configure that generates the gtk2hs-confg.h from gtk2hs-confg.h.in based on tests in configure.ac. I've never been able to reproduce it and when others have helped me investigate we did not find a solution or indeed a cause.
If you'd like to do some digging it'd be much appreciated. I'm cc'ing the gtk2hs-users list just in case someone else has already diagnosed this.
I had such (or very similar) problem when I was building gtk2hs on windows. The reasons of not finding the version numbers were problems with carriage return character (CRLF<->LF). Unfortunately I cannot verify this for you since I switched to linux. Peter.
