Use current working directory version of perl module

I am trying to run a perl script and to make it use a module file in the current working directory. I do this because I eventually will need to use the script and module on another machine where I have no control of what or where modules are installed. My problem is that I can get this to work on some machines, but not others.

The script is:

ubuntu@machine-5:/tmp/pig-local$ cat test.pl
#!/usr/bin/perl -w -I ./Text
use Text::CSV_XS ;
print "Hello World\n"

and when executed I get the error:

ubuntu@machine-5:/tmp/pig-local$ ./test.pl 
Can't locate loadable object for module Text::CSV_XS in @INC (@INC contains: ./Text  ./Text /home/ubuntu/perl5/lib/perl5/x86_64-linux-gnu-thread-multi /home/ubuntu/perl5/lib/perl5/x86_64-linux-g
nu-thread-multi /home/ubuntu/perl5/lib/perl5 /etc/perl /usr/local/lib/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/
lib/site_perl .) at ./test.pl line 2
Compilation failed in require at ./test.pl line 2.
BEGIN failed--compilation aborted at ./test.pl line 2.

The current working directory does have the Text directory and the CSV_XS.pm module contained in it. I have checked the md5sum on the file and it is the same as the machine where the script works.

ubuntu@machine-5:/tmp/pig-local$ ls Text/
CSV_XS.pm

My OS is: 

ubuntu@machine-5:/tmp/pig-local$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 12.04.1 LTS
Release:        12.04
Codename:       precise

and these are the different perl env variables set on the machine:

ubuntu@machine-5:/tmp/pig-local$ env | grep -i perl
PERL5LIB=/home/ubuntu/perl5/lib/perl5/x86_64-linux-gnu-thread-multi:/home/ubuntu/perl5/lib/perl5
PERL_MB_OPT=--install_base /home/ubuntu/perl5
PATH=/home/ubuntu/perl5/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
PERL_LOCAL_LIB_ROOT=/home/ubuntu/perl5
PERL_MM_OPT=INSTALL_BASE=/home/ubuntu/perl

When I check to see if perldoc knows about the module in question,

ubuntu@machine-5:/tmp/pig-local$ perldoc -l Text::CSV_XS
./Text/CSV_XS.pm

It thinks the module exists in the current working directory.

Any ideas about how to get this to work?

Thanks

You did not properly install the module. It consists of more than a .pm file. It's not the .pm it can't find, it's the .dll/.so that goes with it.

Look:

@INC contains: ./Text

Guess what is not in that directory? Another directory named "Text". Hence, perl doesn't find Text::CSV_XS there (it would find just plain CVS_XS tho).

Try -I . or:

BEGIN { unshift @INC, '.' }
