Symptom: a.out needs some dll and claims that it can't find
it.  (try ldd a.out, *very* usefull command)

Solution:

Step 1:
Make sure the dll exists
(verify with the famous ls -l command :-)

Step 2:
Make sure your executable (a.out) is looking at the right
places. (By default often only /lib and /usr/lib are looked
for.) Either change your LD_LIBRARY_PATH, or edit
/etc/ld.so.conf (if you know what you're doing). For details
about both options see man ld.so

Hope this helps.
(It has nothing to do with GCC by the way.)
