Can't use DBI and mod_perl together in Cygwin.

I've traced my problem to the TCP/IP stack.  The code below gives:

"Can't get tcp protocol by name at 
/var/www/htdocs/groups/Purch/bin/secure/test.cgi line 12"

<pre>
#!/usr/bin/perl

use CGI;
use Net::Ping;

$query = new CGI;

print $query->header;

print "<html><head><pre>\n";

$p = Net::Ping->new('tcp');
print "$host is alive.\n" if $p->ping("panther2");
print "$host is not alive.\n" if !$p->ping("panther2");
$p->close();

print "</pre></head></html>\n";
</pre>

The DBD code that won't work from within Apache works fine from the 
command line:

   $DBH = DBI->connect("Apache::DBI::Oracle:",q{uid/password@(DESCRIPTION=
     (ADDRESS=(PROTOCOL=TCP)(HOST=server)(PORT=1521))
     (CONNECT_DATA=(SID=databaseSID)))}, "");

When this code is called from within the Apache process (within Cygwin), 
I invariably get a 12545 error.  Again, the DBI apis work fine from the 
Cygwin command-line.  I can connect and run queries without issue so 
long as I don't try it within a CGI script.

Pointers?
