First, why do you set URLDOWNLOAD_USEURLFILENAME to False?  I haven't
tried it but it looks from the code like it wouldn't work very well to
use the full URL as a filename, and it could also be causing the
dependency to be broken if it's not a valid path.

But second, when you do Depends(b, a) you're only saying that the
alias depends on the other alias.  Try this (not tested):
 pkg = env.URLDownload(gtestOutputFile, gtestUrl)
 dir = env.Unpack( ouutdir, gtestOutputFile )
 Depends(dir, pkg)
 a = env.Alias('abc', pkg)
 b = env.Alias('xyz', dir)
