I was able to install Date Popup without first installing the jQuery UI (yes, schoolboy error) - if the jQuery UI module was listed as a dependency for Date Popup, this wouldn't have been possible.

Created a patch for this issue

The problem with this is that since jQuery_UI was not originally a dependency, things can go very badly when upgrading date if jQuery_UI is NOT already installed.

See #22 and #23 here for more:

I think these are the core issues Karen is talking about there:
#228860: Upgrading a module with a newly added dependencies breaks things badly
#799314: Checking/resolving new dependencies for updated modules

I am not sure where the status of those two issues leaves us.... (the first is 'fixed').
So, I will leave this open for now until I find out or if Karen knows more and can chip in.

Thanks for the links - I didn't realise that there was such a problem in the core.

This is not ideal, but I don't have any better ideas than what is already done.
