Cant import __version__

[Adrian]

Hello,
I just installed phpsh using setup.py on a server that I had
previously installed "by hand". It was a while ago and I can't
remember the specifics, but I think it was a "./configure; make; make
install;" routine.

Now when I try $phpsh I get this:

Traceback (most recent call last):
File "/usr/local/bin/phpsh", line 4, in <module>
from phpsh import PhpshState, PhpMultiliner, do_sugar,
line_encode, __version__
ImportError: cannot import name __version__


What did I mess up?

Thanks.
