So I tried exporting the repo to revml instead:
vcp svn:svn://jc.ngo.org.uk:/nik/libtap/trunk/... revml:libtap.xml

I've put the resulting RevML file [2.2MB] here, so that we don't need to
keep hitting Nik's svn repo to debug this:

http://www.yi.org/~faraway/libtap.xml

Also, I've put the vcp.log files that were written for going from SVN->RevML
and RevML->P4 online as well:

http://www.yi.org/~faraway/vcp-svn-to-revml.log
http://www.yi.org/~faraway/vcp-svn-to-revml.log

That process completes fine, but then when I try to import the revml file
into my perforce repository, it crashes with a different error. (I am using
the latest code in public.perforce.com... despite the fact that it was last
edited six days ago, it's saying this is a version from 2004):

$ vcp revml:libtap.xml p4://depot/main/contrib/libtap/...

Patch line disagrees with source line 173:

I tracked down the patch code (VCP/Patch.pm) and replaced it with this, in
desparate hopes that it would work:

sub vcp_patch {
  my($source_fn, $result_fn, $patch_fn) = @_;
  system("patch -p0 --ignore-whitespace $source_fn -o $result_fn < $patch_fn");
  croak "patch failed" if $?;
  return 1;
}

Well, it's output was spammy, but it *did* work! However, once it started
trying to check the files into perforce, it crashed at the exact same spot:

vcp: no DB_File entry for
svn:svn://jc.ngo.org.uk;/nik/libtap/trunk/src/t/plan/Makefile@204
 at /opt/vcp/share/perl/5.8.8/VCP/RevMapDB.pm line 58
	[...]

The *only* occurance of "Makefile@204" in either logfile is that one line...
so it seems like the SVN export is not creating a Makefile@204, yet the P4
import is expecting one?

I'm back to square one. Why would this one file not have this entry?

	Thanks,
