I am unable to install aqbanking (along with other programs such as gnucash or kmymoney2) with the ofx USE flag. I'm not sure if this is specific to PPC or if it's an overlap from ppc64, but I do not have this issue on my x86 computer.
Steps to Reproduce:
1.USE="ofx" emerge -av aqbanking
[ebuild R ] net-libs/aqbanking-4.0.0 USE="python -chipcard -debug -kde (-ofx) -qt3"
[ebuild R ] net-libs/aqbanking-4.0.0 USE="python ofx -chipcard -debug -kde -qt3"
# net-libs/aqbanking and dev-libs/libofx don't have ppc64 KEYWORDS
Seems like an oversight, since they both are keyworded on ppc64
ofx removed; stabilized for 64ul too. Not sure why it was masked because masker did not include a good reason or bug number.
