Monobjc fails in installation in MacOSX El capitan

[LauraLaureus]

I have tried to intall Monobjc because it seems useful but it fails in last step of installation. I'm working on MacOSX El capitan. Has anyone a clue about how to solve this?

I'm getting a successful install, but the assemblies are not listed as registered in the GAC.
/Library/Application\ Support/Monobjc/ is created, and filled with files. But gacutil -l does not list any Monobjc assemblies.

@silasary Did you install it by script or something? I tried to install it by .pkg and fails :(

I just ran the pkg. [Monobjc-6.0.2744.0.pkg (SHA 6f2f6aedb3c9543c8997aa1e818557e31b4e1da3)]
