If you try and run squid-graph without dev-perl/GD built with USE"png" you will get this error: "Can't locate object method "png" via package "GD::Image" at /usr/bin/squid-graph line 990, <STDIN> line 2837026." Suggest adding something like: einfo "Please confirm that dev-perl/GD has been emerged with USE='png'" Reproducible: Always Steps to Reproduce: 1.emerge dev-perl/GD USE="-png" 2.emerge squid-graph 3.squid-graph --tcp-only --cumulative --title="Foo Squid Graph" --output-dir=/root/graphs < /var/log/squid/access.log Actual Results: Error: Writing to file /root/squidgraphs/tcp-access.png Can't locate object method "png" via package "GD::Image" at /usr/bin/squid-graph line 990, <STDIN> line 2837026.

build_with_use() check is what you want - as long as we don't have use dependencies at least
I Thought per the Gentoo Dev Manual: "Currently it is impossible to depend upon 'foo built with the bar USE flag enabled'" Thus i assumed that build_with_use referred to mandatory USE flags for the ebuild only not for dependencies. -Mike
Thank you for report, Mike. Fixed in CVS. (In reply to comment #2) > Thus i assumed that build_with_use referred to mandatory USE flags for the > ebuild only not for dependencies. build_with_use is a function in eutils.eclass which allows to test if package was built with specific use flag or not. Check eclass code for further details.
