OK, we ran into this as well. The problem is that on Windows
the CLASSPATH is actually Classpath, mixed case instead
of uppercase. The pkgIndex.tcl file does not take this into
account. We have already modified the pkgIndex.tcl file
to fix this problem, which is available from CVS (just don't
use the 1.2.5 release tag, it's in the main trunk of the code).
