Re: [Myexperiment-discuss] Problem installing MyExperiment on Windows XP...

[Don Cruickshank]

Hi Martin,

I think this is due to changes in the namespace used by the libxml-ruby gem.
I've found in another module that explicitly putting in LibXML::XML::Node fixes
this problem between the distributions of Linux we use.

Can you please update your lib/rest.rb file and try again?

Thanks,
Don.
