-- Configuring done
You have changed variables that require your cache to be deleted.
Configure will be re-run and you may have to reset some variables.
The following variables have changed:
CMAKE_C_COMPILER= cc
CMAKE_CXX_COMPILER= c++

END LOOP

Reproducible: Always

Steps to Reproduce:
1. # cd /usr/ports/kde4-l10n
2. # make config
3. choose "All languages" in the dialog
4. # nice make package
Actual Results:  
Compilation loops 4ever, output is given above under "details".

Expected Results:  
If s/th is wrong, "make" can abort with an error message, but shall not loop.

WORKAROUND: Manually enable all languages but serbian. 

Hint, maybe not to the KDE config jockeys, but to the FreeBSD ones:
GISYF + RTFM "Recursive Make Considered Harmful": http://miller.emu.id.au/pmiller/books/rmch/

Additional info:
1. If you ever want to see ccache's hit ratio climb as high as 90% with a cache size of 2GB, use ports on FreeBSD... ;)
2. Would be nice one could specify "+Install Aspell dictionary" for all languages once, to avoid beeing asked every few minutes again for the next language.
