objc @3.2.8 Build Error

[zorgatone@…]

After trying a couple times and cleaning the port/updating all the ports, I'm still having trouble installing objc @3.2.8.

I get this error in the build phase:

Macports error log

[cooljeanius (Eric Gallager)]

This is part of what prompted me to ask for an update to 3.2.11: #38326

(at least I think it was this error, it might have been a different one)

[cooljeanius (Eric Gallager)]

Cc Me!

[mf2k (Frank Schima)]

See #53012.

I'm getting a different error now; there's now a -Werror=implicit-function-declaration problem before it even gets to the Objective C error listed originally:
