lbdb: one or more PCH files were found, but they were invalid

[tkren@…]

I encountered the following error while running sudo port install -c lbdb +gpg+ldap:

--->  Computing dependencies for lbdb

Error: Status 1 encountered during processing.
To report a bug, see <http://guide.macports.org/#project.tickets>

The log file is attached.

Please remember to Cc the port's maintainer.

The relevant lines in the log seems to be:

:info:build cc1obj: error: one or more PCH files were found, but they were invalid
:info:build cc1obj: error: use -Winvalid-pch for more information

A new version of lbdb is available; perhaps updating the port would help.

A new version of the port isn't going to uncorrupt Xcode's PCH cache. Launch Xcode.app and choose "Empty Caches…" from the application menu.

unfortunately, this didn't fix the problem. after emptying the Xcode caches and removing the build dir of lbdb, I still get the following build failure:

I tried out version 0.37 of lbdb, but runningmake gives me the following error:

(NOTE: project ABQuery was written by an older Xcode version (38) -- temporarily upgrading it (without modifying project file))

There doesn't appear to be anything that could be done about this Xcode bug in the port. Deleting the PCH cache (/var/folders/zz/zzzivhrRnAmviuee+++++++++++/-Caches-/com.apple.Xcode.0/SharedPrecompiledHeaders in the above example) manually in the terminal is the workaround if doing it through Xcode.app doesn't work.
