Package: libmusicbrainz-ruby Version: 0.2.0-1 Severity: serious libmusicbrainz-ruby fails to build because it cannot find pow in libm:
> cd . && ruby extconf.rb
> checking for pow() in -lm... no
> *** extconf.rb failed ***
> Could not create Makefile due to some reason, probably lack of
> necessary libraries and/or headers. Check the mkmf.log file for more
> details. You may need configuration options.
>
> Provided configuration options:
> --with-opt-dir
> --with-opt-include=${opt-dir}/include
> --with-opt-lib=${opt-dir}/lib
> --with-make-prog=make
> --srcdir=.
> --curdir=/tmp/buildd/libmusicbrainz-ruby-0.2.0
> --ruby=/usr/bin/ruby1.8
> --with-mlib=m
