I use mpop and msmtp. I tried to set up fetchmail many years ago. One deficiency is that it didn't allow downloading email to a file (mbox). I used getmail, which is a Python script, many years ago after giving up on fetchmail. I believe hplip, used for some HP printers including multifunction, depends on Python 2.7, something that needs to be corrected/updated. Or is that already done? Tom

Is that a build-time dependency or is it needed for Firefox to actually run? I suppose you could unmerge Firefox, and install Firefox-bin to find out. -- Walter Dnes I don't run "desktop environments"; I run useful applications

Thanks ! -- in 16 years using Gentoo, I've never come across eclasses.
I see they are listed in /usr/portage/eclass .
Is there a doc which describes what they are & what they do ?
Let's hope everyone involved gets their acts together

What about Firefox ?
-- trying to unmerge Python-2.7 tells me that Firefox-60.8.0 requires
"python 2.7.5-r2:2.7[ncurses sqlite ssl threads]".
That Firefox ebuild does indeed require those flags,
but it also contains "PYTHON_COMPAT=( python3_{5,6,7} )".
What is telling Portage that Firefox needs Python-2.7 ?
