Do I read this correctly? You try to darcs mv something where you specify a 
directory (gsom) in lower case, but you get an error message that reports the 
directory name with the initial letter in upper case (Gsom)?

This is a system that may be using a case-insensitive file system. Darcs have 
had, and possibly still has, some issues with case-sensitive file systems. An 
example of an unresolved issue related to case-insensitive file systems is

  http://bugs.darcs.net/issue253

You may wish to take a look at this issue and, perhaps, other issues related 
to the use of case-insensitive file systems: I get 21 issues as a result when 
using "case-insensitive" as a search string:

And then you may wish to report a new issue for your case.
