This is due to recent pkg-config no longer adding spaces around libs, and Makefile.PL just appending the new libraries, resulting in -lglib-2.0-lpangocairo-1.0 instead of -lglib-2.0 -lpangocairo-1.0 as argument. This patch should fix the issue: https://github.com/voidlinux/void-packages/blob/master/srcpkgs/perl-Pango/patches/fix-pangocairo_libs.patch

Created attachment 415128 [details, diff] Pango-1.226-linking.patch This patch fixes the problem. AFAIK this is what upstream added to the code.
I can't reproduce that $!@# bug. I did install gcc 5.2.0 and switched it on and still, compilation+installation go through fine. :| Should I add the patch nonetheless?

The patch by polynomial-c solved the problem for me. I used dev-util/pkgconfig-0.29.

I have just hit this in stable... and patch from comment #6 works, could it be included please? Thanks
commit c0020a7 (HEAD, master) Author: Patrice Clement <monsieurp@gentoo.org> Date: Wed Oct 28 20:49:20 2015 +0000 dev-perl/Pango: Add patch preventing failure at compile time. Fixes bug 562216. Package-Manager: portage-2.2.20.1 Signed-off-by: Patrice Clement <monsieurp@gentoo.org> create mode 100644 dev-perl/Pango/Pango-1.224.0-r1.ebuild create mode 100644 dev-perl/Pango/files/Pango-1.224.0-linking.patch As usual, give it a go and report back. Thank you.
It works but... why was it added with a revbump? It's only a build time fix, right? Well, if the revbump is kept, it should be fast stabilized Thanks
