Bugzilla Bug 169595

When disabling the ipv6 flag in app-admin/conky-1.4.5, the configure script
breaks on missing glib. Upon investigation, the ebuild sets dependency on
>=glib-2.0 in that case, but the emerge doesn't resolve it:

USE="-ipv6" emerge -pv conky

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

Calculating dependencies... done!
[ebuild  N    ] app-admin/conky-1.4.5  USE="hddtemp truetype -X -audacious
(-bmpx) -ipv6 -mpd -vim-syntax" 0 kB

And I do not have glib installed:

Calculating dependencies... done!
[ebuild  N    ] dev-libs/glib-2.12.7  USE="-debug -doc -hardened" 2,833 kB


Reproducible: Always

Steps to Reproduce:
1. unmerge glib if it was emerged before
2. disable ipv6 flag
3. emerge conky

Actual Results:  
checking for GLIB... configure: error: Package requirements (glib-2.0) were not
met:

No package 'glib-2.0' found


Expected Results:  
Successful emerge (well sort of, the fix from bug:166500 is not in the portage
yet)

Filed as minor, since there's an easy fix (emerge glib manually).

Because you have USE="-X" set; reopen with some compile errors.

I am not sure what you mean. I don't have X and you are not supposed to need X
to compile conky either. When I enable ipv6 the ebuild says that some
port-feature will be disabled. Since I don't need ipv5 and might want that
feature, I compile without ipv6 and then it breaks on missing glib. Since it
doesn't even get to compilation, there is no way for me to provide compile
errors either.

If this is a "feature" then please explain cause I don't get it.

I mean that there's no unresolved dependency; the ebuild *only* depends on glib
if you have USE="X -ipv6" set.

Then that is a bug, since the configure script clearly checks for glib with
USE="-X -ipv6" (see original description). It seems that the glib dependency
should exists even with "-X".
