The following sequence works for me (Debian GNU/Linux Etch):

$ cd glpk-4.43
$ ./configure
$ make
$ make check
$ make install
$ cd ..
$ cp glpk-4.43/examples/sample.c sample.c
$ gcc sample.c -lglpk
$ export LD_LIBRARY_PATH="/usr/local/lib"
$ ./a.out

If LD_LIBRARY_PATH is not correctly set, running a.out causes the
error you mentioned, i.e. "libglpk.so.0: cannot open shared object
file: No such file or directory".
