[ic] Perl module troubles

[DB]

I have an IC server that's running 5.4.2 under Centos 5. I'm attempting
to install 5.6.1 into /usr/local/interchange-5.6.1 so that I can test
before I install per the instructions in the UPGRADE document. I was
able to do this successfully on an identical server.

'perl -v' gives:
This is perl, v5.8.8 built for x86_64-linux

This perl was compiled without threads. 'which perl' gives:
/usr/local/bin/perl

(identical to the other server). My 5.4.2 catalog runs fine.

For the 5.6.1 install, 'make test' gives:

PERL_DL_NONLAZY=1 /usr/local/bin/perl "-Iblib/lib" "-Iblib/arch" test.pl

I tried to

perl -MCPAN -e 'install Bundle::Interchange'

but this poops out after awhile.

Can someone help me diagnose/correct what I suspect is a problem with
one or more of my perl modules?


Thanks!
