mono 2.6.7 does not work with WinForms

[rudloff@…]

I am not sure this a MacPorts bug, but the mono port does not work when a program uses Windows.Forms :

Unhandled Exception: System.ArgumentException: The requested FontFamily could not be found [GDI+ status: FontFamilyNotFound]

Could it be a missing dependency ?

Testcase

[macsforever2000@…]

Why did you attach a Windows executable?

[rudloff@…]

It is a C#/.net executable (from the ​WinForms samples) that shows the problem with mono.

The same bug exists under Snow Leopard too

I have Microsoft Sans Serif installed and it's seen via fc-list

Is this still a problem with mono @2.10.6? If so, you probably need to report it to the developers of mono; mono does not have a maintainer in MacPorts.

No response; assuming fixed based on upstream changelogs.
