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

Hello, i tried to install Neomail, a web based perl email client; when i start to install, it tells me it requires MD5 module; so i downloaded it from CPAN but when i type perl Makefile.pl it gives me an error: 
 
Checking if your kit is complete...
Looks good

Error: Unable to locate installed Perl libraries or Perl source code.

It is recommended that you install perl in a standard location before
building extensions. Some precompiled versions of perl do not contain
these header files, so you cannot build extensions. In such a case,
please build and install your perl from a fresh perl distribution. It
usually solves this kind of problem.

(You get this message, because MakeMaker could not find "/usr/lib/perl
+5/5.8.0/i86-linux-thread-multi/CORE/perl.h")

Well; i tried to search on PerlMonks for this argumet and i find 'Unable to locate installed Perl libraries' Error and tye answer but i can't understand: i have the /usr/lib/perl5/5.8.0/i86-linux-thread-multi/CORE/ directory but perl.h doesn't exist: it contains only "libperl.so"; if i type perl -V i can't find $Config{privlib} nor $Config{archlib}.
What have i to install?
i hope i explain well my problem; sorry for my english...

    Where'd you get your perl? Did it come with your OS? If so, what OS/distribution is it? If not, did you compile it yourself or get it as an external package?
[reply]
      Ok sorry for few information. I get perl with my OS. It is Linux Mandrake 9.0

        Hey, I grabbed the rpm of perl-base from mandrake 9, and it indeed lacks perl.h. No worries -- it's part of the perl-devel package (which you presumably don't have installed). Go grab it here.

    If you have CPAN installed you should try using that to install and manage modules as it makes life quite a bit easier.

    Try -
         perl -MCPAN -e 'install Some::Module'

      Except in this case, it wouldn't help. CPAN and MakeMaker both use Config;, and if Config.pm is corrupted, it's not gonna help one bit.

      I run a Win32 PPM repository for perl 5.6x+5.8x. I take requests.

        Gads! How could I have missed that?
        thanks for the correction

      I've tried to type perl -MCPAN -e 'install MD5' and it started installation. Then i retype it but it responds:
      Read more... (2 kB)
      Probably have i to be root?

        No, I think that Improv is correct...you need to install the perl development package for Mandrake.....which is where I get off, as I am strictly a Debian guy and  apt-get install perl just isn't going to help you much ;-)
