Is it not possible to include them in the distro?

I got everything from CVS, installed it and I still get

X:\pyx\examples>python hello.py
Traceback (most recent call last):
  File "hello.py", line 6, in ?
    c.writetofile("hello")

This file is here:
c:\miktex\texmf\type1\bluesky\cm\cmr10.pfb

tstrip builds fine. I have no idea what it does..

No, they get left around even if everything works.

I use the mathpazo package (palatino with math) all the time.
I tried it in the hello.py example after the from pyx import *


X:\pyx\examples>python hello.py
Traceback (most recent call last):
  File "hello.py", line 2, in ?
    text.preamble(r"\usepackage{mathpazo}")
  File "c:\python23\Lib\site-packages\pyx\text.py", line 2230, in preambl=

    self.execute(expr, *args)

    raise TexResultError("unhandled TeX response (might be an error)", se=
lf)
pyx.text.TexResultError: unhandled TeX response (might be an error)
The expression passed to TeX was:
  \usepackage{mathpazo}%
  \PyXInput{5}%
After parsing the return message from TeX, the following was left:
  *! Undefined control sequence.
  <*> \usepackage
                 {mathpazo}%


Sorry I can't be more helpful -- I don't know the internals of latex that
well.
Let me know if you need more info.
