Hi Walt, It isn't anything like fsck, etc. The machine is healthy in all other respects (that I know of and have tested) and everything is actually working. It's only the list option that's failing. eselect actually knows that binutils is set correctly. It just won't like it. c2stable ~ # eselect binutils show x86_64-pc-linux-gnu-2.21.1 c2stable ~ # eselect binutils set x86_64-pc-linux-gnu-2.21.1 !!! Error: Profile "x86_64-pc-linux-gnu-2.21.1" is already active! exiting c2stable ~ # eselect binutils list !!! Error: Pattern does not match any installed version of binutils! exiting c2stable ~ # Actually, I don't think it's that hard to compare files or directories that are supposed to be consistent on various machines. That's what rsync does to decide what to sync. The trick is getting the options correct which is usually my downfall. Anyway, in this case I compare the /usr/share/eselect/modules directory on my local (failing) machine with one of the other machines here in the house. In the first compare I look at the binutils file specifically which passes. In the second compare I look at everything in the modules directory which shows one mismatch which in this case is that the remote machine doesn't actually have a wxwidgets.eselect file. I cannot tell that until I log into the remote machine to determine the difference. mark@c2stable ~ $ rsync --dry-run -crv /usr/share/eselect/modules/binutils.eselect mark@k2:/usr/share/eselect/modules/binutils.eselect Password: sending incremental file list sent 55 bytes received 12 bytes 19.14 bytes/sec total size is 7796 speedup is 116.36 (DRY RUN) mark@c2stable ~ $ rsync --dry-run -crv /usr/share/eselect/modules/* mark@k2:/usr/share/eselect/modules Password: sending incremental file list wxwidgets.eselect sent 1095 bytes received 15 bytes 246.67 bytes/sec total size is 147613 speedup is 132.98 (DRY RUN) mark@c2stable ~ $ A little bit of Google suggests you can diff the files themselves using something like: diff <(ssh -n me@testserver cat /home/me/source/worksforme.php) <(ssh -n me@clientserver cat /home/me/source/worksforme.php) I have not tested this but suspect it probably works fine once you get everything right. HTH you or someone in the future, Mark
