Dear William, thank you very much for your reply, it does seem to be the same type of bug. However, and I apologize for being dense here, it is not immediate to me how to proceed practically to apply the patch from within the ports framework. Also, I still wonder why the patch hasn't been incorporated in the tree given that the bug is known.... thanks again giuseppe On Mon, Oct 11, 2010 at 4:07 PM, William Bulley <web@umich.edu> wrote: > > Giuseppe Pagnoni wrote: >> >> I am resending this because it seems to me a really critical bug >> (prevents you from using OpenMotif or lesstif applications), but >> apparently nothing has been changed since last july.
