Making a wild guess: your gcc is newer than the one used to check
reportlab. The newer version could be more strict than the previous
ones.

You could post the version of gcc (gcc -v) so that people at reportlab
can diagnose the problem more properly.

Even though I'm not an expert of easy_install, if you've older
versions of gcc installerd, maybe you could try to force it to use an
older version using an "export CC=/usr/bin/gcc-<something>"; however,
I'm not sure this will not cause troubles with python itself. Again,
making guesses.
