Is anyone else seeing this? On my 10.5.1 laptop with a cast-sensitive filesystem, I am unable to compile the latest python25...
Macintosh:include sck$ sudo port upgrade python25
--->  Building python25 with target all
Error: Target org.macports.build returned: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_python25/work/Python-2.5.1" && make all " returned error 2
Command output: Python/mactoolboxglue.c:425: error: 'cobj' undeclared (first use in this function)

nor MPlayer versions...

In file included from vo_macosx.m:9:
vo_macosx.h:13:32: error: QuickTime/QuickTime.h: No such file or directory

So, I did a full find of my drives, and did a case insensitive search and found...
Macintosh:include sck$ grep -i "QuickTime/QuickTime.h" ~/find.txt
577661        8 -rw-rw-r--    1 _devdocs wheel         218 May  2  2007 /Developer/Documentation/DocSets/com.apple.ADC_Reference_Library.CoreReference.docset/Contents/Resources/Documents/documentation/QuickTime/QuickTime.html

Just wondering if its a tweaked config of mine, or is there a case issue?
