  didn't find it /lib but no-matter...

 I'm building perl5.005.03 and perl5.005.057, for use with mod-perl
1.20 and sybase.

    RH> What specific problem do you want to solve ?

 As debian was installed a number of programs are installed which have 
a dependency on the 1.85 library. When I replace the symbolic link 
  /lib/libdb.2.so => libdb.2.7.5, a number of programs broke

   every network sensitive tool complained about /usr/lib/libnss_db.so 
and not finding function dbopen.
   cron stop working because symbolic libaries did not load properly.
   mail stop working because exim could not find dbopen.

 ( dbopen is the function name in 1.85 which conflicts with sybase
usage, where db_open is the name used by libdb 2.1.X or greater.)
  
  perl expects to find -ldb and /usr/include/db.h to have the same
version number and that version number > 2.4.6.

  How can I provide that functionality (have -ldb of release 2.7.5)
without breaking the current system which requires -ldb be 1.8.5?
