I was able to work around this issue by disabling tcache via
malloc.conf:

ln -s 'tcache:false' /etc/malloc.conf

pkg would install, but /usr/local/sbin/pkg was mislinked:
http://ix.io/1xlt

So as a workaround to that, I just mv'd /usr/local/sbin/pkg to
/usr/local/sbin/pkg.bak and replaced it with a symlink to
/usr/local/sbin/pkg-static.

I've now successfully compiled and installed a few ports. I've also
updated the wiki to document the two workarounds described above.

It seems this type of mislinking happens with more than just pkg:

(pkgconf-1.0.1) /usr/ports/devel/pkgconf/work/stage//usr/local/bin/pkgconf - 
required shared library ./.libs/libpkgconf.so not found

So I wonder if it's happening with all dynamically-linked executables
in the ports tree.
