Version 26.5 of sci-mathematics/gimps is available for download. This is still a beta for the new version. It contains several bugfixes for bugs in version 26.4: 1) Pentium 4s and Celerons with L2 cache size of 256K or less choose a length 4M FFT when they could use an FFT between 1600K and 4M in size. Fixed in next release. 2) The on screen message reporting that errors have occurred during the LL test was wrong. The counts for "SUM(INPUTS) != SUM(OUTPUTS)" and "ROUNDOFF > 0.4" were reversed. Fixed in next release. 3) Dual-boot users running a 32-bit and 64-bit executable on the same exponent may experience "Unable to initialize FFT" message. This happens when prime95 writes an FFT size to worktodo.txt and that FFT size is only supported by just one of the two executables. For example, the 2240K FFT length is supported for 64-bit Core 2 but not 32-bit Core 2. Fixed, somewhat inelegantly, in 26.5 -- unimplemented FFT lengths are ignored when worktodo.txt is read. 4) Prime95 will sometimes inexplicably unreserve exponents. I think this happens when prime95 incorrectly calculates the CPU speed. Version 26.5 will only use a new slower CPU speed measurement after several slower CPU measurements. Hopefully, this will resolve the unreserve problem caused by a single erroneous CPU speed measurement. 5) Prime95 would lose the how_far_factored and tests_saved information on PRP= lines in worktodo.txt. Fixed in 26.5. 5) Prime95 did not offer an option to delete P-1 save files when a work unit completes. Fixed in 26.5. 6) Prime95 did not fully understand Sandy Bridge CPUID output. Fixed in 26.5. 7) Prime95 did not accurately report the CPU speed. Fixed in 26.5. 8) At startup, the workers threads do not start up properly until communication with the server completes. If you have a large worktodo.txt file, this will result in wasted CPU time and many "use count" error messages. Fixed in 26.5. 9) Time estimates for trial factoring to 2^79 and above were incorrect. Fixed in 26.5. 10) Occasionally, P-1 stage 2 would report 100% complete before stage 2 completed. This bug has been around forever. I've finally found the cause! Fixed in 26.5 build 2. 11) Worktodo.txt was not updated properly when P-1 completed for a PRP test. Fixed in 26.5 build 3. This is not yet a candidate for stable (unless upstream deems it so), but it would be nice to have it in ~arch for beta-testing. Version 26.4 should be dropped.
BTW: just renaming the ebuild works (at least for amd64).
Use only binaries downloaded after February, 22nd, 08:00 GMT, they're a later build (build 5) which fixes a few more minor bugs. BTW, as you can see in http://www.mersenneforum.org/showpost.php?p=253325&postcount=87 this could be a candidate for stable in due time.

Added to CVS. Thanks for reporting the new version.
