Hi,

I'm trying to emerge seafile-pro-server from then pentoo overlay. But I have problems to fulfill the python dependencies correctly.
Code:
# emerge -1a seafile-pro-server

These are the packages that would be merged, in order:

Calculating dependencies... done!

The following USE changes are necessary to proceed:
 (see "package.use" in the portage(5) man page for more details)
# required by seafile-pro-server (argument)
>=www-apps/seafile-pro-server-7.0.13 -python_targets_python2_7

Would you like to add these changes to your config files? [Yes/No]

After adding the suggested line I'm running into the next problem:
Code:
# emerge -1a seafile-pro-server

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N    ~] www-apps/seafile-pro-server-7.0.13  USE="-fuse" PYTHON_SINGLE_TARGET="python2_7" PYTHON_TARGETS="-python2_7"

Would you like to merge these packages? [Yes/No] Yes

It requires python 2.7. But why I have to set -python_targets_python2_7?

After a reboot I could emerge seafile-pro-server without problems.

For the record, this issue is (probably) due to changes in the python-single-r1 eclass.

For details see: No more PYTHON_TARGETS in single-r1.
