is graphics/linux-cairo broken?

[Rick C. Petty]

Like many people, I upgrade my ports by building everything in a staging
area using chroot(1).  For the last few days I've had a terrible time
with this process because I've been bumping into a problem with the
graphics/linux-cairo port (there may be others??).

I'm running 6.3-PRERELEASE and I've csup'd my world/kernel and staging area
multiple times today.  Here's the output when I hit linux-cairo:

~~~~~~~~~~

Obviously any further commands break with similar undefined symbols.  The
problem is that FreeBSD's ldconfig is being run (instead of Linux's) to
merge /compat/linux/lib in with the FreeBSD bits.  Since I was thankfully
running in a chroot, I can just remove the /var/run/ld-elf.so.hints file
but I also have to remove /compat/linux/lib from my ldconfig directories.
The FreeBSD libs shouldn't be mixing with the Linux libs, right?

My guess is linux-cairo shouldn't be setting USE_LDCONFIG or it should
redefine LDCONFIG to use ${LINUXBASE}/sbin/ldconfig and perhaps run it via
chroot.  If I'm correct, this isn't the only port which is broken.  A
bunch of other linux ports do something similar and in different ways (see
"grep -i ldconfig /usr/ports/*/linux*/Makefile").

How come I'm the first to be hosed by this?  Or maybe I'm missing something
obvious?
