couchdb fails during start after Xcode 4.6.1

[public+macports@…]

After upgrading to Xcode 4.6.1 Couchdb no longer starts. The error was:

dyld: Symbol not found: __cg_png_create_info_struct
  Referenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
  Expected in: /opt/local/lib/libPng.dylib

As a temporal solution I modified the installed launchctl file removing the DYLD_LIBRARY_PATH section

<key>DYLD_LIBRARY_PATH</key>
<string>/opt/local/lib:$DYLD_LIBRARY_PATH</string>

After removing that line, the ImageIO framework seems to load just find and CouchDB server starts

Thanks for the ticket. In the future, please Cc relevant port maintainers and use WikiFormatting in your ticket descriptions.

One of the many places where using DYLD_LIBRARY_PATH is a bad idea. It should probably just be removed completely.

Regression of #22102, removed in #37632 as included comment suggested it was no longer needed and appeared to build fine without it. Obviously wrong about that. Patch is forthcoming.

Patchfile attached.

Better to do this with patches. I’ve committed a fix in r104103; let me know if it works.

I think this can be closed at this point. Francisco, please add a comment to reopen if you run into this issue again.
