[MacPerl] DBI errors

[Mike Schienle <mgs@ivsoftware.com>]

Hi all -

I'm having a hell of a time getting DBI to work on a CSV file and 
would really appreciate some help. I've listed the error messages, 
code, input data file and output. I have the DBD-CSV-0.1022 README 
and "Programming the Perl DBI" book if it's easier to reference a 
page from one of those. I also have about 6 other Perl books 
(including MPPE) on the desk so chances are you can make a reference 
to a page from another book and I'll find it.

Error messages:
# DBD::CSV::st execute failed: # Error while reading file :test.csv: 
Operation not supported on socket, <GEN0> chunk 1.
File 'Aleutian:Applications:MacPerl:site_perl:DBD:CSV.pm'; Line 201
# Couldn't execute statement # Error while reading file :test.csv:

     'col_names' => ["esID", "transID"],
     'eol' => "\r",
     'sep_char' => ",",
     'file' => "test.csv"
};
