Good.  Before the "/////" (shell prompt) you should see the output of
tramp_file_attributes.  But there is no output.  So now the next step
is to figure out why does tramp_file_attributes not produce any

In the *debug tramp/foo* buffer you should be able to see the source
code of that shell function (it invokes Perl), and then you can
change it to invoke "perl -d" or something.

If it is not easy to figure out why tramp_file_attributes fails, then
it might also be possible for Tramp to make a check whether it
fails.  Then Tramp could abstain from using it.  There is a function
in Tramp which looks for a working Perl, this function could be
augmented to check for your case, too.  But I have no idea how to
figure out if your case happens.  (I mean, without actually trying
tramp_file_attributes, but the check should be before that shell
function is defined.)
