I am using texlive from freebsd-texlive project:

and this error happens on both 8.2 now 8.3-BETA1 boxes and not in 9.0
box :(  It appears to be issue 19 here:

Ideas as to how to solve it?  I have removed print/texlive-pgf/ port
and reinstalled it and it still gives same error.  Relevant
information from thread in issue 19 in case it is important:
