Hi Clive:

Sorry about the inconvenience. It seems that Debian (and thus Ubuntu I guess) does not supply that library at all. I guess we'll configure the binaries without it in the future. Not sure why it doesn't work on the Mac, where apparently our build system has the lib, but we'll just change the build option there too.

I will open a bug for this, and it should be resolved in the upcoming 1.5.0 release.

In the meantime, can you build directly from source? That should be quite simple and will resolve all issues with missing libraries.

Best,
Torsten
