cpan -> check module dependencies

['chris']

hi

I've installed a lot of perl modules using cpan on my debian etch stable.
I forced some modules instalations because of errors.
howto check for module dependencies if is everything OK now ?

kind regards
chris

Hi 'chris', please see:

Shalom,

It would also be helpful long term if cpan maintained a respository supporting apt-get and yum for Red Hat Linux.

It is worth the time to ask them to do that and deal with dependency issues.

thanks,

I've installed libmodule-scandeps-perl:

# apt-cache search Module-ScanDeps
libmodule-scandeps-perl - perl module to recursively scan Perl code for dependencies
# apt-get install libmodule-scandeps-perl

but howto use libmodule-scandeps-perl now ?

Hi Chris:

> I forced some modules installations because of errors.

Why would you do this?

If you use :

# perl -MCPAN -e shell

The module detects module builds which have prerequisites. You can elect to build the prerequisites automatically ('follow'); ask you for confirmation ('ask'); or simply 'ignore' them.

You should be able to remove any existing '~/.cpan/CPAN/MyConfig.pm' and then when you rerun, choose more appropriate settings.

You might want to reinstall your locally-installed modules. You can find them with:

# perldoc perllocal

Regards!

some modules must be forced, for example if you try to install Net::SFTP under debian etch stable, you get a lot of very nice errors:

# perl -MCPAN -e 'install Net::SFTP'
