Syntax Error in lvalue.pm?

Ragged Robin has asked for the wisdom of the Perl Monks concerning the following question:

Hey guys, I'm a perl newb but I'm pretty baffled at this issue. I'm currently running Perl 5.18.1 on a NAS and have lvalue.pm installed at a custom location at: /var/services/web/debug/lib/Class/Accessor/ However compiling my .cgi I get a syntax error with it:

Software error:

When I pass this with the perl test I get:

TARDIS> perl -c -e "test Class::Accessor::Lvalue"
-e syntax OK

Not sure how this makes any sense at all, I downloaded the lvalue module straight from the CPAN website (I had to manually install).

perl -c -e "test Class::Accessor::Lvalue" This will test if your program will compile. It will not include Class::Accessor::Lvalue in your code snippet. To test that you should try `perl -MClass::Accessor::Lvalue -e 1` If there's no error then everything is OK. Not sure how this makes any sense at all, I downloaded the lvalue module straight from the CPAN website (I had to manually install). Why did you do manual install? There might be your problem. You should use cpan client to do the whole process for you. I recommend App::cpanminus. System default CPAN is also OK, but it's slightly slower. Also, if this doesn't work for you, try your system-specific package installer.	[reply] [d/l]

From the looks of it, Class::Accessor and Lvalue are two separate CPAN modules. My guess is that you don't want Lvalue.pm under the Class/Accessor directory. You probably want Lvalue.pm under `/var/services/web/debug/lib` By the way, I'm not sure if your test is doing anything useful: `perl -c -e "test Class::Accessor::fooooooooooo" -e syntax OK` [download]	[reply] [d/l] [select]

Class::Accessor::Lvalue uses Want which is partly written in C, and thus requires compilation. Use a CPAN client to install it, and all the dependencies will be automatically downloaded and installed. Manually downloading and installing modules is enough of a bother than most Perl experts rarely attempt it. Just use a CPAN client. toby döt ink	[reply]
