Steps to recreate: 1. Install VMWare Workstation 5.5 on a Windows host 2. Build a Gentoo guest with xorg-x11-7.0-r1 3. Attempt to install VMWare tools: The "config" step builds "vmhgfs" just fine, but croaks trying to do the X part with the message Detected X.org version 7.0. Problem extracting verion of X.org Execution aborted I rather doubt this is a Gentoo problem -- I'll simply drop back to xorg 6 something and it should go away. But I didn't see anything in the VMWare documentation saying that Workstation 5.5 couldn't handle xorg 7.0.
So you mean that it isn't compatible as a *guest* not that vmware-workstation doesn't work on Gentoo... Well, it sounds more like an issue with the VMware tools, which means it needs to be taken up with VMware themselves.
