doxygen build failure with bob

Hi,
On NetBSD-11 amd64 I'm building packages with bob, however doxygen
consistently fails to build:

============

Building doxygen manually from the pkgsrc tree works fine. I also
checked bulktracker and noticed that doxygen builds on amd64, but
fails on evbarm with the same issue:
http://victory.netbsd.org/pkgsrc/packages/reports/2026Q1/evbarm64-11.0/20260427.2238/doxygen-1.16.1nb1/build.log

Has anybody seen this kind of failure before?
Is there any known fix, or missing configuration option?
