The ebuild for dev-perl/math-pari-2.010500-r1 has a hard depend on pari 2.1.5 (DEPEND="=app-sci/pari-2.1.5"), which has since been updated to 2.1.5-r2 and the 2.1.5 ebuild has been removed from portage Reproducible: Always Steps to Reproduce: 1. emerge sync 2. emerge math-pari Actual Results: Calculating dependencies \ emerge: there are no masked or unmasked ebuilds to satisfy "=app-sci/pari-2.1.5". !!! Error calculating dependencies. Please correct. Expected Results: Should have build pari 2.1.5-r2 if necessary and then emerged math-pari. Changing the dev-perl/math-pari-2.010500-r1 ebuild as follows: DEPEND="=app-sci/pari-2.1.5" to DEPEND=">=app-sci/pari-2.1.5" solved the dependency problem and math-pari build successfully
you break it, you buy it phosphan. ;-)
Already bought. Everything should be fine with math-pari-2.010500-r1.ebuild CVS version 1.6 which is in portage now. If you need a quick fix, just change the = in the DEPEND line to a ~. Thanks for the hint.
