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.

This appears to be the standard mistake of specifying libraries via LDFLAGS instead of LIBS. The LDFLAGS variable references the libraries via a `pkg-config --libs` expression instead of listing them explicitly. Moving the pkg-config call to the right variable should push it down to the end of the line and solve the problem.
