When trying to compile xmlrpc-c-1.18.02 with USE=abyss compilation fails on a missing include. The following is the error message: thread_fork.c:6:18: error: wait.h: No such file or directory Looking at the existing patches in the files directory, there is xmlrpc-c-1.06.09-darwin.patch which contains the needed fix to compile xmlrpc-c-1.18.02 with USE=abyss. Please see to applying this patch to 1.18.02.
done, thanks!
