Comment:

 Your compiler is too old.

 gcc-4.2 is rebelling here at the use of the keyword
 {{{
 __bridge
 }}}
 which is part of a bridged cast used with Automatic Reference Counting
 (ARC) in current objective C/C++.  I believe this was introduced somewhere
 around Apple clang 4.0, LLVM 3.1 or so (Xcode 4 in OS X 10.6).  This code
 does, in fact, build on the 10.6 buildbot but apparently not on 10.5 and
 earlier.

 This is filter code using CoreImage so the simplest thing to do here is to
 disable the corresponding filters.  To do this add the following lines
 after the configure.args section of the Portfile
 {{{
 configure.args-append    --disable-filter=coreimage \
                          --disable-filter=coreimagesrc
 }}}

 If this works for you, I'll incorporate the appropriate changes on this
 end.  As usual, I'm not able to test on 10.5 so I need your help.

 Thanks.
