Compiling Extractor_projects fails "cannot find source files:"...

I just cloned the mangoszero master branch from github and attempted to run the "getmangos.sh" script under server/linux/ and am receiving the following errors.  Everything seems to compile and run fine except the Extractor_projects directory where everything bombs out.  Below is the output that is generated immediately after the last user input on the getmangos.sh script:
