I completed and tested ebuild for gpc-20020402 (rc5) for Gentoo Linux. It has been commited and now is available. Frank, thanks for help!
If there are any gentoo users I would appreciate some testing :). The instructions are pretty standard: 1. unmask the package by commenting out gpc entry in /usr/portage/profiles/package.mask (I will keep it masked for a few days until I am completely sure) 2. emerge gpc
to test it you can unpack gpc tarball and run testsuite (4 tests will be skipped since librx is not installed).
