...and the current version is 0.7.1 so it's overdue for a version bump.
It looks like the linker isn't being told where the libpthread.so library is. Using the --enable-threads=pthreads configure option fixes things nicely: src_compile() { ./configure \ --host=${CHOST} \ --prefix=/usr \ --infodir=/usr/share/info \ --mandir=/usr/share/man \ --enable-threads=pthreads || die "./configure failed" emake || die #make || die }
I think 0.7.1 fixes that, and it's recently committed. Please test it. If you still experience problems, make out a new bug for 0.7.1 instead.
