devel/doxygen broken on macppc-current?

Building "devel/doxygen" on macppc-current produces a broken binary.

When 'doxygen' is later run during the build of "www/tidy", it segfaults:

[...]
cd /var/tmp/pkgsrc/www/tidy/work/tidy/htmldoc &&  /var/tmp/pkgsrc/www/tidy/work/tidy/console/tidy -xml-help > tidy.xml &&  /var/tmp/pkgsrc/www/tidy/work/tidy/console/tidy -xml-config > tidy-config.xml &&  xsltproc tidy1.xsl tidy.xml > tidy.1
cd /var/tmp/pkgsrc/www/tidy/work/tidy &&  doxygen htmldoc/doxygen.cfg
[1]   Segmentation fault (core dumped) doxygen htmldoc/...
*** Error code 139

Stop.
[...]

and the following is logged on the system console:

trap: pid 23129.1 (doxygen): user read DSI trap @ 0x4 by 0x1b8532c (DSISR 0x40000000, err=14)

The resulting core file produces:

Core was generated by `doxygen'.
Program terminated with signal SIGSEGV, Segmentation fault.
