Hi,
  the problem with your script when run on windows is likely caused
by spaces in filenames or directories messing up the "split".
If you're put Tcl packages into a directory (e.g. your "e:/vmdextensions/tcl"
example below), you can simply use:
  lappend auto_path e:/vmdextensions/tcl

Then use "package require mypackage" and it will automatically be found if
it is in a subdirectory within your "e:/vmdextensions/tcl".

I'm not sure what went amiss with the script you posted below, as that could
also work, so long as you're careful to avoid spaces in filenames etc.
The script as-written will break if you have any filenames containing spaces.
Here's a fixed version that should also work with spaces:

foreach ext [glob E:/vmdextensions/tcl/*.tcl] {
  puts "sourcing: $ext"
  source $ext
}

If you have any errors within the scripts that you're automatically
sourcing, having that extra "puts" call in there will help you figure
out if the error is in your vmd.rc file, or rather a problem in one
of the scripts that you're sourcing. Once you eliminate the problem(s)
you can simply comment out the puts call.
