though I'm not ruling out something obvious that I may have missed
programmatically speaking, this isn't my first CGI and though I haven't
tried Kevin's suggestion yet about checking for  unecessary spaces, I have
checked for  invisibles caused by the FTP or HTML transfer and/or file
system EOL markers. The logs file only contains the error message above
plus the path to what generated it. The CGI runs from the command line so
there aren't any problems as far as the path to the Perl interpreter is
concerned

I have another script which uses the following declarations:

#!/usr/bin/perl5 -w
use strict;
use diagnostics-verbose;
use CGI;
use CGI::Carp qw(fatalsToBrowser);


but the script dies without generating Perl warnings of any kind, only the
system errors quoted above

I tried generating the content header manually (thinking CGI.pm might be
missing) but had the same result - no output except for the errors.

thanks for the suggestions guys however, and I'll go back over the scripts
to see if there's anything I might have missed that you've brought up
