I'm trying to install parallels tools on a centos 4.4 vm. I have: 2009 17" macbook pro Parallels 4.0 build 3844 The installer log is below and seems to have problems with X-modules. The installer log generates the following errors, and I can't find anywhere on the web a solution. I have also tried Centos4.7 with similar results, but I have Parallels tools successfully installed on Centos 5.2. Can anyone help?
