Subject: Re: Build an OpenMP in Jumbo 1.7.9-5

I am working to finalize a new OpenMP version for Lion that also works for 10.6 (Snow Leopard).  You should be able to compile a version just fine by enabling the OpenMP settings in the Makefile of Jumbo 1.7.9-5.  Make sure to set the compiler to gcc-4.2 on the CC line in the Makefile as Lion uses gcc-llvm by default which is buggy and will produce build errors on the Jumbo build.
