New Update(2010.12.04): Messed around a bit on my linux system and a 'smaller' fix is to only install:
'libmono-system-data2.0-cil' it is considerably smaller than 'mono-complete'.
UPDATE: this issue can be fixed by installing 'mono-complete' package. FAQ and installation instructions updated...
Some linux users are experiencing the following issue;
** (./Servify.exe:2746): WARNING **: The following assembly referenced
from /path/to/servify/Newtonsoft.Json.Net20.dll could not
Assembly: System.Data (assemblyref_index=1)
Public Key: b77a5c561934e089
The assembly was not found in the Global Assembly Cache, a path listed
in the MONO_PATH environment variable, or in the location of the
executing assembly (/path/to/servify/).
I'm working to resolve it asap. My suspicion is that the MONO package in ubuntu 10.10 has changed and as a side effect of that, a dependency in Servify is not being met. If my fix is successful I will update the Servify package asap.
