Windows XP has SystemDrive and SystemRoot environment variables,
while Windows 98 don't seem to have them.
a quick workaround is to set the SystemRoot environment by hand (it should
point to the Windows system directory; usually c:\windows. iirc, you have to
edit AUTOEXEC.BAT or run the MSCONFIG utility to set them).
alternatively, you can add the following fix to your application code:
import os
os.environ["SystemRoot"] = os.environ.get("windir", "c:\\windows")
(put it *before* the wxplot import code)
a better fix is to make the freetype font_lookup code a bit more robust.
