What/ where is cygXt-6.dll ? A newly made app can't find it!

[Keith Gunderson <kegunder at avalon dot net>]

Hello.  I was taking a crack at building Xephem 3.5.2 on my newly 
updated Win2000 / cygwin box (with Lesstif.)

The program will make just fine, but when I run it the standard "path 
error" dialog appears complaining that it can't find cygXt-6.dll  From 
what I've seen, this is the Xt widget set... or no? 

Any pointers on where this stuff is or how I should make the app to 
statically link in Xt would be appriciated.  I remember seeing the 
libXt.a library on the system, BTW.

Doing a cygcheck on the app causes the following:


$ cygcheck.exe xephem

Thanks for the help.
