[Mapserver-users] PERL mapscript undefined symbol woes

[Joe Bussell]

Greetings Listers,
    I have a Debian box with PERL5.8 and mapserver-3.6.5.  I have had 
great success in the past with this box, but something in my build went 
awry.  The compile for mapserv and then perl/mapscript completed without 
error.  The object is also generally useful when using dump.pl and even 
some live map rendering under apache.  The symptom that I observed is 
that whenever the process needs to carp out something it segfaults and 
dies.  I ran ldd with the -r option and observed an interresting clue 
(see below).  Does anyone have any ideas how the Perl_* symbols are 
defined?  Why would they not be found?  Should the list of *.so include 
libperl.so?  Any ideas on getting out of this mess?
