Question Regarding Perl Mapscript

[Gabriel A Weaver]

Hi all,

I am trying to install mapscript for perl and run into the following error:

[terminal: ]$ perl -e 'use lib 
"/web/cgi-bin/Progs/lib/5.6.0/i386-linux"; use mapscript; my $map = new 
mapObj("DBs/MapData/world.map"); if ($map == null) { print "UTOH!";} 
else { print "IT WORKS!";}'

Unfortunately, I keep getting "UTOH", indicating I have a null pointer 
instead of a mapObj object.

So far I have: a) verified that the world.map file is in the proper location
b) checked permissions
c) rebuilt mapscript.pm after re-swigging.

Note, I am building with an older version of MapServer, a version from 
1999, because I heard that MapServer 4 maps may not be fully compatible 
with mapserver 3 data.  Any help you could provide would be much 
appreciated.

Thanks,

Gabe
