new developer: cssutils error in hello_world plugin

[sdm7g]

OK: I got the development environment working and was able to insert
some print statements and see the results in the terminal after running
'calibre-debug -g'

For the next step, I tried loading the hello_world plugin.
One attempting a conversion, I get the following error:

RuntimeError: You need cssutils >= 0.9.9 for calibre

I see that cssutils is NOT in the sources downloaded with bzr,
although there are .pyo files for cssutils in the /Application/calibre.app
bundle. (I'm working on MacOSX)

So is the issue that there is no cssutils in the source tree ?

Or is the problem that the cssutils in the Application bundle is the wrong version? (I'm running calibre 0.8.48)

And how do I fix this ?

Update to calibre 0.8.49, then you will be able to run the source

Thanks. That fixed it.

I was used to getting prompted for automatic updates, so I thought my app was up to date.
Oddly, I got the version 0.8.48 from checking 'get info' on the app in the Finder.
But the version at the bottom of calibre's preferences pane shower 0.8.49

I manually downloaded and installed a new version and they both show 0.8.49,
and the plugin works.

The version calibre shows is the version of the source code you are running, that's why there will be a little asterisk next to the version number in calibre when you run from source.
