Conversion from CVS to Mercurial fails

[Stephen Rasku]

I am trying to convert my CVS repository to Mercurial and it fails:

$ hg convert --datesort NS-2000 NS-2000-hg
initializing destination NS-2000-hg repository
cvs rlog: Logging NS-2000
cvs rlog: Logging NS-2000/BASE_STATION

request for non-existent rev 1.1 in file BASE_STATION/tu_pack.h
connecting to /var/backup/mercurial/cvs-import/
cvs [rlog aborted]: received broken pipe signal

The specified file was originally added on a branch.  That's why
revision 1.1. doesn't exist.

I am trying to reorganize the CVS layout to match modules we have set
up in CVS.  If I keep the original CVS locations it works but if I lay
it out how I want it to be imported int Mercurial I get the above
error.

Any ideas?
