your dynamic linker cannot find libgd.so.0. why?
I have no linux system in handy, but I suppose
you can use ldd command to check which libraries rateup depends.
(and I bet you see "libgd: not found"...)
read the man page of ld and ldd.
I suppose you can find a clue for dynamic library (shared objects) management.
on solaris system, I do such like
setenv LD_LIBRARY_PATH /usr/local/lib:/opt/gd/lib:/some/other/dir
to notice the dynamic linker which directories to look for the library.
check which environment variable you should setup.

solution3 is in effect only when you have libgd.a (for static linking).
