add mailing list in 0.38

[calvin]

I'm getting an error when trying to add an (idx) mailing list.  I have added the line in mailinglist.c to add the NULL.  Now instead of no data, I get an Internal Server Error. The logs: ezmlm-make: fatal: dir and dot must start with slash   Other details - vpopmail 4.9.4, qmailadmin 0.38, ezmlmidx 0.53.324 (same results with 0.53.40), Mandrake-Linux Can provide full configure line if necessary Any suggestions? Thanks, Calvin
