Problems running cpan_update from perl v5.6.0-RC1

[Steve Kelem]

I'm running
perl -MCPAN -e shell
with your perl on Cygwin 1.0, with the latest downloads for cygwin,
and all of your rpms installed.  This is on NT 4.0 SP6, Pentium III 550,
256M memory.

If I type "install Bundle::CPAN" to the cpan shell prompt, I get the
following errors:
cpan shell -- CPAN exploration and modules installation (v1.52)
ReadLine support available (try ``install Bundle::CPAN'')

Parsing config.in...
Looks Good.
Checking if your kit is complete...
Looks good
Note (probably harmless): No library found for -lz
