Total: 1 package (1 reinstall), Size of downloads: 0 kBI have also noticed in some post here that "eselect python" is supposed to be deprecated and "USE_PYTHON" should be used instead, but I could not find any clear explanation about it.
And finally, I would like to emerge python 2.7.1 (in parallel to 2.6.5), because I need it for my work, leaving 2.6.5 as default one. Is it safe? Because, interestingly, when I simply unmask 2.7.1 in portage and try:
Code: Select all
core-i3 risa # emerge -pv "<dev-lang/python-3.0"
These are the packages that would be merged, in order:

Total: 1 package (1 in new slot), Size of downloads: 0 kBEDIT (2010-12-11): Following problem has already been solved - see follow ups
Unfortunately, when I run it it fails pretty fast with:
