when emerging hplip the configure process fails when checking for cups-devel
as defined by the USE-Flags it should not check for cups, becaus it is NOT
installed 

output from emerge/configure:

this bug also affects hplip-0.9.8-r2

install of hpijs works fine 

bug-wranglers@gentoo.org

Indeed so. This affects all versions of hplip in the tree.
My proposed solution is to make hplip hard depend on cups. Objections?

If you can find no other way to build it w/o cups that is ok.

I would make cups harddep now and if somone comes up with a solution it can
still be changed. hplip deps are broken currently and need to be fixed asap.

Done, cups is now a hard dependency. If anyone has a better fix, please make
sure to let us know.

Thanks for reporting!
