I am quite happy and relieved a solution has been found for this CMake-2.6 issue. Jerry played a big role in solving this issue; I don't think a solution would have been possible without his many patient answers for all the requests for information that I was relaying to him from the CMake list. The final solution was a simple, but essential two-line patch to Modules/Platform/Darwin.cmake to replace -Wl,-compatibility_version, and -Wl,-current_version with -compatibility_version and -current_version. The -Wl, passes that option directly to the linker with no interpretation by gcc. It's amazing the old version worked for some linkers (although not the linker associated with macada gcc) since according to the gcc documentation the names of the options are -compatibility_version and -current_version without the -Wl, i.e., these options are meant to be interpreted by gcc rather than passed directly to the linker.
