Trouble Rebuilding IDE

[khoward]

I'm having an issue rebuilding the IDE (installing a package).  Everything compiles fine until it gets to the "Build IDE" portion and it errors with a fatal: unable to open file <screwed path to idemake.cfg>.  The path is missing all of the directory slashes.  It worked in Laz 2.0.0.
So, instead of this:.
C:\Users\khoward\AppData\Local\lazarus\idemake.cfg -dx86_64 .
I'm getting this: .
Fatal: Unable to open file C:UserskhowardAppDataLocallazarusidemake.cfg -dx86_64 .
Note the missing slashes. 
Windows 10 18.03 64bit.
Lazarus 2.0.2 64bit.
Stock FPC (3.0?).
Thanks for any suggestions!
