Most likely something to do with _py.sh not being strictly POSIX compliant. The 
enforcement of POSIX strictness varies by shell and by OS release. For example, 
in Ubuntu 16.x (xenial), when I manually test the cmp_version function from 
_py.sh, it works fine. However, the dash (Debian Almquist shell) man page on 
that host also says:

The current version of dash is in the process of being changed to conform with 
the POSIX 1003.2 and 1003.2a specifications for the shell.

(Notably, xenial is not the most recent Ubuntu release. Also notably... dash 
has no cli option that reports its version number? That's unfortunate...)

ANYWAY: the issue is surely one of these: https://wiki.ubuntu.com/DashAsBinSh

I'll take a pass through and see what I can find...

Thanks, Guido..

caldav@util:~/CalendarServer/master$ /bin/bash bin/run -n
/Users/caldav/CalendarServer/master/bin/_py.sh: line 104: [: # 1 "": 
integer expression expected
/Users/caldav/CalendarServer/master/bin/_py.sh: line 109: [: # 1 "": 
integer expression expected
Using /Users/caldav/CalendarServer/master/.develop/virtualenv/bin/python as 
Python

Starting server...
/usr/bin/python2.7: can't find '__main__' module in ''

Same result.

Here’s a snippet of _py.sh that is generating the error:

#
# Compare version numbers
#
cmp_version () {
  local  v="$1"; shift;
  local mv="$1"; shift;

  local vh;
  local mvh;
  local result;

  while true; do
 vh="${v%%.*}"; # Get highest-order segment
mvh="${mv%%.*}";

if [ "${vh}" -gt "${mvh}" ]; then   <— line 104
  result=1;
  break;
fi;

if [ "${vh}" -lt "${mvh}" ]; then
  result=0;
  break;
fi;

Without having looked at the script at all can you try

   /bin/bash bin/run -n

since /bin/sh is dash.
