I'm reporting this bug because the package in summary fails to build when forcing --as-needed on through spec files (check out http://blog.flameeyes.eu/2008/11/14/problems-and-mitigation-strategies-for-as-needed for details).
Please note that this bug _might_ apply to -Wl,--as-needed in LDFLAGS as well; in both cases it should be fixed. Also, if this is due to the package in question not respecting user-defined LDFLAGS, you should get to fix that too.
Check the attached build log.

Looking into the package there seems not to be a serious test suite but only one file test.c which seems to be a relict of some testing experiments.
I would recommend adding 'RESTRICT="test"' to the ebuild.
The package does also not respect LDFLAGS. That must still be fixed.
