Question

On a ubuntu server, with everything installed (checked against another pc where this works just fine) When trying to run warble on one of my jruby projects, I get this error:

all libraries and required gems seem to be there. Google didn't help, and the strange thing is that on other pc this works fine...

Solution

What version of libxml2 are you using?

I had this same problem on OSX (leopard) which ships with libxml-2.6.x. I installed libxml-2.7.3 and the error went away. More info here: http://wikihub.berkeley.edu/x/zgXNAQ
