Monodevelop MONO x64 amd_x64 amd64

Even though mono compilation was successful on my x64 OpenSuse installation, I stumbled upon the following error when opening/compiling .NET project:

Mono.Unix.Native.Syscall ---> System.EntryPointNotFoundException: Mono_Posix_Syscall_get_at_fdcwd

The solution turned out to be adding the following switch to MONO's autogen script:
--libdir=/usr/lib64

My whole compilation script was:
#!/bin/sh
cd /home/jmd/monoFoka/
./autogen.sh --prefix=/usr --libdir=/usr/lib64
make
make install

The whole body of the exception:
System.TypeInitializationException: An exception was thrown by the type initializer for Mono.Unix.Native.Syscall ---> System.EntryPointNotFoundException: Mono_Posix_Syscall_get_at_fdcwd
