I downloaded the source for perl and tried to configure it for dynamic
module loading (using the dl_dld.xs file as suggested by the build) but
when I complile I get a missing header file.

Can anyone help me ?

Thanks,

In the Configure file, look for:
  
  linux) dflt='-rdynamic' ;;

and change it to 

  linux) dflt='-Wl,-E' ;; 

(that is capital W, little letter l as in larry wall) 
(found in the source rpm at linuxppc.org)
