in thread Can't build modules that load Socket.so

Hi thanks for the reply, ldd outputs: 
-bash-3.00$ ldd /usr/local/lib/perl5/5.12.0/sun4-solaris/auto/Socket/S
+ocket.so
        libc.so.1 =>     /lib/libc.so.1
        libm.so.2 =>     /lib/libm.so.2
        /platform/SUNW,Sun-Fire-V445/lib/libc_psr.so.1

I have also used ldd -r and I get the following: Main thing imo: 
        symbol not found: inet_pton             (/usr/local/lib/perl5/
+5.12.0/sun                                             4-solaris/auto

Do you think that this is causing the problem? because the error log states that "...symbol inet_aton: referenced symbol not found at..." or does that point to XSLoader.pm? All of the info:

Re^3: Can't build modules that load Socket.so
by Anonymous Monk on Sep 21, 2010 at 07:55 UTC
    libc.so... is supposed to define inet_pton, so I've no idea why thats broken ...

    also Socket.so is supposed to link to libperl.so, I also have no idea why thats broken.

    Are you sure you're not mixing the system perl with perl you compiled yourself?

    Shot in the dark, try 

    "export LD_LIBRARY_PATH=/usr/local/lib"

    You might also be able to glean some hints from Not able to load module though @INC contains it

    A real sysadmin ought to be able to help you resolve this :)

      Truth is that the machine I am working on had Perl5.8.2 installed and I had to install a newer version because some applications required higher versions of core modules. The new version was installed from a package by the sysadmin together with some libs , he then symlinked the old /usr/bin/perl to /usr/local/bin/perl5.12.0 . Now, the applications depending on perl are running smoothly and I had no trouble with building 8-12 modules since then, with the exception of this one. I'll post my "perl -w" just in case you see something is wrong or missing.

        I would try to recompile Socket then ... might as well go for 5.12.2 :)
