Ok got gcc installed, now the configuration script is throwing errors. Here is the output. Trying to find a suitable vmmon module for your running kernel. None of VMware Workstation's pre-built vmmon modules is suitable for your running kernel. Do you want this script to try to build the vmmon module for your system (you need to have a C compiler installed on your system)? [yes] What is the location of the directory of C header files that match your running kernel? [/lib/modules/2.4.7-10enterprise/build/include] Extracting the sources of the vmmon module.

For more information on how to troubleshoot module-related problems, please have a look at "http://www.vmware.com/download/modules/modules.html". Execution aborted. On the website the suggest downgrading gcc. I applied for tech support but they need to register my s/n. The dumb web registration setup leads to a null page. Thanks Colin Kilbane
