Citrus Perl: problems trying to load additional modules

[HelenCr]

Dear esteemed PerlMonks

After a long struggle, I gave up fixing Alien::wxWidgets 2.9.4 installation on StrawberryPerl 5.16.3¹, and instead downloaded and installed Citrus Perl². I changed system and user path to point to the Citrus Perl installation.³

But now, I need to install again several modules.

When using CPANPLUS trying to install DateTime, I'm getting errors: see (abridged) log:

CPAN Terminal> i DateTime

+03)

Error installing 'DateTime'

Update:  Solved. See this post below: perlmonks.org/?node_id=1034103

The three main problems I see here are (quoting from log above):

1. Could not find or check module 'Module::Signature' [THIS MAY BE A PROBLEM!] at F:/Win7programs/Citrus/perl/lib/CPANPLUS/Module/Signature.pm line 51;
2. Warning: ExtUtils::CBuilder not installed or no compiler detected
   and:
3. [ERROR] Module 'DateTime' needs perl version '5.008001', but you only have version '5.16.3' -- can not proceed

I am getting similar errors trying to install some other modules.

What to do?

Many TIA - Helen

¹ (Big disappointment. Experts advice didn't help, although implementing all their suggestions, I kept getting a perl.exe crash in: wxbase294u_gcc_custom.dll, see here: perlmonks.org/?node_id=1033560)
² I've "relocated" the Citrus Perl installation according to the documentation, and used the utility to: a. install the MinGW compiler and b. update to wxWidgets 2.9.4
³ Having several Perl installations is perfectly "legal" and covered by documentation. (For example, see here: perlmonks.org/?node_id=1033038)
