Reinstalling PERL and module problems : esp Scalar::Util::weaken

Zones: Perl Programming Language, Linux Administration, SuSE Linux

Tags: Perl, OS: SUSE Enterprise Server 10

Hi,

I recently updated (autoupdate) my system (SUSE Enterprise 10) and I am facing problem with Perl. Some of my programs such as a DAS server (proserver)and apache2 which I used to run well arent doing so now.
While trying to run Proserver, I get an error
------>
bioch2022:/usr/local/ensembl/Bio-Das-ProServer/eg # ./proserver -c myconfig.ini is only avaliable with the XS version at /usr/lib/perl5/site_perl/5.8.8/Compress/Zlib.pm line 9
BEGIN failed--compilation aborted at /usr/lib/perl5/site_perl/5.8.8/Compress/Zlib.pm line 9.
Compilation failed in require at ../blib/lib/Bio/Das/ProServer.pm line 17.
BEGIN failed--compilation aborted at ../blib/lib/Bio/Das/ProServer.pm line 17.
Compilation failed in require at ./proserver line 14.
BEGIN failed--compilation aborted at ./proserver line 14.
------------>
apparently while checking on this, it turns out that the vendor installed Perl isnt that good and causes such problem (asking for XS version and problems with Scalar::Util::weaken). I am thinking of reinstalling Perl from source code.
1. I would like to know if this is advisable and would experts recommend this.
2. I also want to know why updating the SUSE changes the configuration such drastically.
3. Importantly I want advice on Uninstalling PERL safely and reinstalling perl again. Especially I am worried about the directory structures in SUSE that I fear if reinstalling them would bother rest of the already installed software programs that are dependent upon PERL.

Thanks in advance.
