[ale] Question building Perl-5.005.02

[John M. Mills]

Hello - I'm trying to build the referenced package from Sunsite sources
(the version in SRPM wasn't up to what I needed), and I get two surprising
errors at library link time:

1) Generic libm stuff not found:

Even though I identified "-lm" among the libraries to link, it doesn't
seem to be used.  If I re-enter the link command manually with a trailing
'-lm', then those are resolved. @#$!!

2) Missing 'main':

 -- Why is this in a library linkage anyway, and what should I do here? 

I'm running RH4.2 and libc5

TIA - mills
