Hi Gary,
sorry for the late answer. I*'m using in my Cygwin the bash (/bin/bash) 
and also on your little example the print
line returns always None although the myfile exists.

Scons return:
$ scons
scons: Reading SConscript files ...
--None
scons: done reading SConscript files.
scons: Building targets ...
scons: `.' is up to date.
scons: done building targets.

and the files:
$ find .
.
./.sconsign.dblite
./SConstruct
./subdir
./subdir/myfile

I have replace the env.FindFile with a own function, that runs
for root, dirs, files in os.walk(l) :
it is slower, but this returns the correct values
