Hi Deivit,
Well, to use mojoportal on Mono at all with a release version, you would need to start with the mojoportal-pgsql-for-mono release files, then grab the *.Data.dll files from the bin folder of the sqlite release and paste them into the bin of the pgsql-for-mono release. This is because the web files require a special build, you can't use the windows versions on Mono as it has some unsupported things like web parts in it. If you work with the MonoDevelop solution mojoportal.mds, it is already configured to leave out unsupported things. I build with it to make the for-mono package but I only make one version of the package, not one for each db platform (it would be ideal to do that but also more work)
I will also say that though it should work in theory, I have never tested with sqlite on mono myself, I've only tested it on windows. On linux I test only pgsql and mysql myself.
Possibly at some point we will have an installer to make things easier.
Best,
Joe
