Imagine I had simply forgotten to unmask the abi_x86_32 USE flag for
kbproto but was attempting to emerge unstable (or unmasked abi_x86_32)
libXt. In fact, if I un-unmask kbproto (so that abi_x86_32 is masked),
unmerge kbproto and attempt to emerge libXt:
dynamic71 mattst88 # emerge libXt -vp
These are the packages that would be merged, in order:
Calculating dependencies... done!
emerge: there are no ebuilds built with USE flags to satisfy
"x11-proto/kbproto[abi_x86_32(-)?,abi_x86_64(-)?,abi_x86_x32(-)?,abi_mips_n32(-)?,abi_mips_n64(-)?,abi_mips_o32(-)?]".
!!! One of the following packages is required to complete your request:
- x11-libs/libXt-1.1.4::gentoo (Change USE: -abi_x86_32)
(dependency required by "x11-libs/libXt-1.1.4" [ebuild])
(dependency required by "libXt" [argument])
It suggests that I turn off abi_x86_32 for libXt rather than telling
me to turn the flag on for kbproto!
Portage prints other things intelligently:
mattst88@dynamic71 ~ % FEATURES=test emerge dev-python/py -vp
