ruby: Cannot create main thread

[Ross]

Hi

I have an old machine running 7.3-STABLE. I tried to install
portupgrade from ports, but installation failed on ruby dependency
with message "Cannot create main thread". I then just pkg_add'ed ruby.
Now when I simply run "ruby" in the console it dies with the same
message. What could be the reason? How do I make it work?
