I'm a bit confused right out of the gate here. Any assistance is gratefully appreciated.

Hi there

OK, there seem to be 2 problems here.  They're both bugs, even if only in documentation :(

First, it appears from the first syntax error that JCR will no longer run on Python 2.4 - you'll need version 2.5 or 2.6.  I've been testing (and running) on 2.5 for a long time now, so I'm afraid I wasn't aware of that one.  I'll update the documentation.

Second, the install documentation is incorrect about including 'svn' in as one of the extras - after writing that, I found out that pysvn isn't available as an easy_install package.  So, you should install using the command line
    easy_install -f . jcr[mysql]

Again, I'll update the documentation for both of these - sorry for the confusion.  I hope it works for you now.

Very good. That helped me get past that point.
A couple of catches in getting to that point though:
1) python2.5 is not native in current builds of RHEL/CentOS5.3 (its python24), so I had to install parallel
Here's a great site that I found the rpms that helped me with this: http://www.geekymedia.com/python_26_centos.html
It has rpms for both 25 and 26
2) You have to re-install ez_install using the newly installed python25 command rather than the old 2.4 python.

the command 'easy_install-2.5 -f . jcr[mysql] now ran through with no issues.

Thanks for the help, and hope my return info helps!

Thinking about it further, I hadn't intended to stop JCR working on Python 2.4, so I'll probably try to support 2.4 again in the next release (JCR 0.7.1).

Thanks very much for the information - most useful.
