Bugzilla Bug 176901

When emerging net-www/gnash-0.7.2_p20099999, configure fails to detect boost
libraries when they are built without the 'threads' USE flag.

Reproducible: Always

Steps to Reproduce:
1. USE="-threads" emerge boost
2. emerge gnash

Actual Results:  
        ERROR: No BOOST development package installed!
               You need to have the BOOST development package installed
               to compile, or install libboost-thread-dev and
               libboost-date-time-dev (using apt-get) or boost-devel
               (using yum).
Warning: You need to have the Ming development and utilities packages installed
to run most of the tests in Gnash testsuite. Some of the tests will be run
anyway.
Warning: You need to have the MTASC compiler packages installed to run some of
the tests in Gnash testsuite.
        Z flags are: default include path
        Z libs are: -L/lib -lz

configure: error: Please install required packages

Expected Results:  
ebuild pkg_setup() should check if boost was compiled with threads support.

Suggestion:

if ! built_with_use -a dev-libs/boost threads; then
        eerror "dev-libst/boost has to be built with the 'threads' USE flag
        die "dev-libs/boost not built with threads"
fi

thanks, I added this to the ebuild with a little extra fix :)
