In Eagle 6.4, I'm getting an error rmessage "Parameter 'rank' is only valid in board editor" when running a scr generated by Ultralibrarian (free version) from the microchip site, on the file MCP1700X-XXXXX_MB.bxl. It seems to stop before generating the polygon for a thermal pad. Any suggestions?? (Couldn't upload bxl file)

OK, I've had a look at the free Ultralibrarian program you mention and the
script file it generates for the MCP1700X-XXXXX_MB
In a word, unimpressive.
Looking at the script produced I can see the problems you are having and
others you may have.
Your reported error is because it attempts the following line in the package
editor.
Change rank 0;
Which is illegal in the package editor. Remove the line and the script runs
to completion. But........
The next issue is the polygon it attempts to draw. It does not end up at
the starting point so the polygon is rejected by Eagle. (never drawn).
Add (-12 -52) to the end of the polygon line (just before the 
that will
get you back to the beginning.
So that draws the polygon now but there's another issue
The polygon does not extend to include the origin of the centre SMD so you
will get DRC errors unless you manually extend it.
Drag the bottom of the polygon down below the centre of the SMD.Its a bit
concealed by the SMD but you can see where the bottom is because the SMD is
a little wider.
If you have trouble, turn off all layers except layer 1Top
Ultralibrarian is an old program and would not know this is a requirement
for Eagle v6.
Numerous (7) text objects are placed on top of each other. Took a bit of
working out what was going on there. Just drag them apart.
So there's the answer. HTH
