Eudora, Snow Leopard and Kerberos

I upgraded to OS X 10.6 "Snow Leopard" yesterday. A smooth upgrade except for one thing.

Eudora 6.2.4 for Mac OS X works on 10.6 (provided the optional Rosetta PowerPC-emulation code is installed), but not with kerberos.

To use kerberized POP, Eudora depends on the Code Fragment Manager library "Kerberos" which is part of the MIT Kerberos Extras for OS X package.

The actual library is installed to /System/Library/CFMSupport/Kerberos and is a 983k file last updated in 2003. It's labeled version 4.2.

If the MIT Kerberos Extras for OS X have been installed, and thus this library is installed, Eudora will fail to launch with the following errors:

Launch failed with error code -2821 (cfragInitFunctionErr) for application /System/Library/Frameworks/Carbon.framework/Versions/A/Support/LaunchCFM App


Eudora can be launched by removing the library. But then kerberos-enabled POP cannot be accomplished.
