Updating texlive-base with portupgrade fails (sort of)

[Carmel]

Using "portupgrade-devel-20130718,3" installed from the ports system,
attempting to update "texlive-base" always ends like this:

--->  Build of print/texlive-base ended at: Sun, 25 Aug 2013 15:25:25 -0400 (consumed 00:11:57)
--->  Updating dependency info
--->  Modifying /var/db/pkg/texlive-full-20120701/+CONTENTS
--->  Upgrade of print/texlive-base ended at: Sun, 25 Aug 2013 15:25:28 -0400 (consumed 00:12:00)
--->  Session ended at: Sun, 25 Aug 2013 15:25:28 -0400 (consumed 00:12:19)
/usr/local/lib/ruby/site_ruby/1.9/pkgtools/pkgtools.rb:828: stack level too deep (SystemStackError)

I have attempted to reboot the system and then start the update
process; however it doesn't make any difference. Even though it appears
as if the port has been updated, when I run "pkgdb -aFv", I am greeted
with this:

[...]
Checking texlive-base-20120701_7
Checking texlive-full-20120701
Stale dependency: texlive-full-20120701 -> texlive-base-20120701_8 (print/texlive-base):
Disclose depends for texlive-full-20120701
--->  Modifying /var/db/pkg/texlive-full-20120701/+CONTENTS
Fixed. (-> texlive-base-20120701_7)
[...]

This is the only package that "portupgrade" seems to be chocking on. I
used "portupgrade" to initially install the complete "texlive" package,
so I am not sure why it is suddenly have problems.
