Version 25.8 of sci-mathematics/gimps is available for download at the URL above. Numerous bugfixes WRT to the latest version. I have no idea whether the x86 version is linked to libcurl.so.3 or not, so I don't know if we still need the binary patch. Sadly I don't have much time to test it this time.
Added to CVS, thanks for notifying us about the new version.
