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

Is anyone familiar with this problem? A Google search turns up some notes -- enough for me to verify things with a test -- but I'm not sure how to fix things.

The problem is this: When using modules that use Crypt::Random, I get errors like this:
"makerandom" is not exported by the Crypt::Random module at /usr/local +/lib/perl5 /site_perl/5.6.1/Crypt/Random/Generator.pm line 12 "makerandom_itv" is + not exported by the Crypt::Random module at /usr/local/lib/perl5/sit +e_perl/5.6.1/Crypt/Random/Generator.pm line 12 "makerandom_octet" is not exported by the Crypt::Random module at /usr +/local/lib/perl5/site_perl/5.6.1/Crypt/Random/Generator.pm line 12 Can't continue after import errors at /usr/local/lib/perl5/site_perl/5 +.6.1/Crypt/Random/Generator.pm line 12 BEGIN failed--compilation aborted at /usr/local/lib/perl5/site_perl/5. +6.1/Crypt/Random/Generator.pm line 12, <GEN0> line 1.

I get this trying to use Net::SSH::Perl. I can reproduce it with this code:

use strict; use Net::SSH::Perl; use UNIVERSAL; # <-- THIS LINE CAUSES THE PROBLEM my $host = 'XXXXXXX'; my %opts = (port => 22, debug => 1, protocol => 2); my $ssh = Net::SSH::Perl->new($host, %opts);
My own code doesn't include that use UNIVERSAL line but if I search what I've installed from CPAN I find a lot of modules that do. If I take that line out, the errors disappear. That seems to be the source of the problem. But I have not found a fix referenced anywhere -- I can't remove all the ones in the CPAN modules I found. Even if I did, I wouldn't be able to upgrade without checking every one I download. This seems like something other monks should have hit somewhere along the line ...

This is Perl 5.6.1 on a Solaris 2.8 platform. I did some limited testing on a 5.8 Perl platform (also Solaris 2.8) and got the same thing. Any help appreciated.

    You upgrade UNIVERSAL by hand. See this thread (UNIVERSAL.pm).

    MJD says "you can't just make shit up and expect the computer to know what you mean, retardo!"
    I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).

    Yes, that did it. Thanks.
