[Gnumed-devel] python-hl7 dependency

[Jerzy Luszawski]

Hi,

Another minor problem I got when running from VCS tree was dependency on
python-hl7.
When this library is missing the client throws unhandled exception.

------- terminal output ---
.========================================================
| Unhandled exception caught !
| Type : <type 'exceptions.ImportError'>

----------- end of terminal output ----

This was easy to handle - I just installed it, but could not find any hint 
about this prerequisite in documentation (wiki). 
Perhaps check-prerequisites script should test for its presence?
