I stumbled upon an error while compiling MONO:
mono CS1566: Error reading resource file `big5.table'
It turned out that I had moved the catalog with MONO source code without saving permissions and omitting hidden files - I just packed them folder with GUI KDE compress tool.
When you want to move the source to another machine: use good old console tar.
tar cvzpf compressed.tar.gz ./folderToCompress
tar xvzpf compressed.tar.gz
