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

Hello Monks,

I am trying to install the RSPerl module to itnerface with R, and I get this rather odd error when testing it: 

perl -I../share/blib/arch -I../share/blib/lib -MR -MRReferences -e 'pr
+int "hi"'
Can't load '../share/blib/arch/auto/R/R.so' for module R: /usr/local/l
+ib/perl5/site_perl/5.8.0/i686-linux/auto/Apache/Request/Request.so: u
+ndefined symbol: ap_null_cleanup at /usr/local/lib/perl5/5.8.0/i686-l
+inux/DynaLoader.pm line 229.
 at -e line 0
Compilation failed in require.
BEGIN failed--compilation aborted.

Having found this a bit baffling I duplicated the same installation on an identical machine, without mod_perl installed and it worked just fine.

My understanding of Perl's handling of .so modules is a little limited - could someone shed soem light on what's going on and, hopefully, how to fix it?

Thanks

Re: RSPerl conflicts with mod_perl?

    The installation process does not start with the error, what happened before? DBD::Sybase

      Not much, I followed theinstructions provided with the R/S-Perl package - compiled R with --enable-R-shlib, installed RSPerl with --with-in-perl; all of this worked as advertized, no errors of any kind. At this point, the above test works on the machine sans mod_perl, but produces the above error on the one that has mod_perl installed.

      I just don't know what perl is doing at this point, so I don't know where to look for a solution (and getting rid of mod_perl isn't exactly an option). Why would R.so have any interaction whatsoever with Apache/Request/Request.so?
