Bug prevents you from compiling MONO 3.4.0

If you got following error while you try to compile MONO by yourself from the source tarball, it means your version of library (3.4.0) misses one file in its tar ball.  (source)

/usr/bin/install -c -c -m 644 targets/Microsoft.Portable.Common.targe  ts/usr/lib/mono/xbuild/Microsoft/Portable/v4.0/Microsoft.Portable.Comm  on.targets   /usr/bin/install: cannot stat 'targets/Microsoft.Portable.Common.targ  ets': No such file or directory

I'm not big fan of Microsoft frameworks especially for the programming language like ASP or C# though, I happened to use a binary of C# on my linux box (Sabayon, variation of Gentoo). Of course, there is a framework for C# in linux named MONO - it means monkey in Spanish which explains their icon design in sourceforge - and current stable version is 3.4.0.

There will be newer version coming soon thus this problem will be solved eventually though, the current version of mono cannot be compiled directly from the download tarball. To solve this problem, https://bugzilla.xamarin.com/show_bug.cgi?id=18690 you should generate a file name "Microsoft.Portable.Common.targets" under the directory "mcs/tools/xbuild/targets" with following contents then compile again.
