I was frustrated trying to figure out how to get subversion installed on my OSX machine so that it would be compatible with Eclipse. I wanted to go with the JavaHL svn adapter but I had already installed svn using homebrew.
I tried to reinstall svn with homebrew like this but got an error:

$ brew install --universal --java subversion
   Error: subversion dependency neon not installed with:
     --universal

There are several dependencies that need to be uninstalled before installing subversion again with –univeral and –java options
For me it was this:

$ brew rm neon
$ brew rm sqlite
$ brew rm serf

Then this worked:

$ brew install --universal --java subversion
