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

Update: Solved. See this post below:
perlmonks.org/?node_id=1034103The three main problems I see here are (quoting from log above):
- 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;
- Warning: ExtUtils::CBuilder not installed or no compiler detected
and: - [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
(running on Windows 7 64 bit, Wx version 0.9921, wxWidgets version 2.9.4)

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)
