Eclipse on a mac, was working fine adding new modules until I Installed Text::CSV_XS which Eclips doesn't recognise as added to @INC For instance

use strict;
use SOAP::Transport::HTTP;

SOAP::Transport::HTTP::CGI->dispatch_to('C2FService')->handle;

BEGIN {

    package C2FService;
    use vars qw(@ISA);
    @ISA = qw(Exporter SOAP::Server::Parameters);
    use SOAP::Lite;

    sub c2f {
        my $self     = shift;
        my $envelope = pop;
        my $temp     = $envelope->dataof("//c2f/temperature");
        return SOAP::Data->name(
            'convertedTemp' => ( ( ( 9 / 5 ) * ( $temp->value ) ) + 32 ) );
    }
}

use SOAP::Transport::HTTP; is marked as error if I comment it out use SOAP::Lite; is in turn marked as an error, not found etc the usual if a module is not installed. Both are installed with CPAN and

$ perl -c soap-test.pl 
post-code-check.pl syntax OK

Perl is fine CPAN tests are all pass, the code works, only EPIC lags behind.

$ pwd && ls 
/opt/local/lib/perl5/site_perl/5.12.4/SOAP
Client.pod      Lite            Server.pod
Constants.pm        Lite.pm         Test.pm
Data.pod        Packager.pm     Trace.pod
Deserializer.pod    SOM.pod         Transport
Fault.pod       Schema.pod      Transport.pod
Header.pod      Serializer.pod      Utils.pod

And if I have use errors in the start of my files the rest of the source is not error checked..
