I'm using Eclipse, and I installed the emonic plugin for C# and the .net. When it autobuilds a project I get this error:


Mono 3.5 Profile (mono-3.5) is not installed, or not correctly configured.

Framework directory '/usr/lib64/pkgconfig/../../lib/mono/3.5' does not exist.

Also the "build all" and "build project" buttons a greyed out.

mono --version
