Bugzilla Bug 152393

sci-libs/fftw-2.1.5-r1 compiles fine with as-needed but rfftw has unresolved
symbols :

I get the following in the configure checks for rezound :

-lpthread >&5

With the patch that will follow, everything is fine.

In CVS. Thanks.

bah running eautoreconf made that patch useless since it's applying to
makefile.in

Created an attachment (id=114998) [details]
patch to makefile.am

finally fixed in cvs.
