MysterX, DrScheme, and Execute (revisited...)

["Anton van Straaten" <anton@appsolutions.com>]

Using a freshly-downloaded and built exp-tagged version of the entire PLT
Scheme source tree (downloaded Wednesday night), I'm having a problem with
MysterX and DrScheme.  The following line will "Execute" once in the
DrScheme GUI:

	(require (lib "mysterx.ss" "mysterx"))

but when I Execute it a second time, I get the following error:

	require: unknown module in:
|,f:\dev\plt-exp\collects\mysterx\private\mxmain|

I'm running this on Windows NT 4.0, and I built plt with MSVC 6.0.

Do I have some kind of build error, or is this a variation on the previous
anomaly with MysterX/DrScheme in which the second Execute in the DrScheme
environment didn't work in some cases?  (Except now it's not working in any
cases.)
