Problems compiling in snow leopard

This is currently on of my problems:

/usr/bin/gcc-4.2 is unable to create an executable file.
If /usr/bin/gcc-4.2 is a cross-compiler, use the --enable-cross-compile
option.
Only do this if you know what cross compiling means.
C compiler test failed.
If you think configure made a mistake, make sure you are using the latest
version from SVN.  If the latest version fails, report the problem to the
ffmpeg-user at mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.err" produced by configure as this will help
solving the problem.

Any tips?
