I did my normal (approximately) weekly emerge sync/update today, and the update failed: emerge complained about a conflict between perl 5.22 and 5.24. There were a bunch of perl modules that required 5.22, but others required 5.24.
After a bit of messing around, I just uninstalled all the ones that required 5.22 (and then uninstalled whatever apps required those modules). This took numerous iterations of 'emerge --pretend --depclean' and 'emerge -C <something>' and 'emerge -auvND'. After 10-15 minutes of this, the update ran without conflict, and then I reinstalled whatever apps I had uninstalled. Now update the next machine... same conflicts. This time I paid closer attention to the emerge output and added '--backtrack=30' as it suggested. Then the update worked ran no problem. -- Grant Edwards grant.b.edwards Yow!
