You may have to do this anyway.

In my experience, setting the environment variable with $ENV{SYBASE}='whatever' within a BEGIN block sets it too late, at least when using DBI with DBD::Sybase.

I've had some success with something like this (which, BTW, makes a program nearly impossible to debug)

BEGIN {
  #need this so you don't recurse indefinitely:
  if ( not exists $ENV{SYBASE_SET} ) {
    $ENV{SYBASE_SET} = 1;
    $ENV{SYBASE} = 'whatever';  # set the variable
    exec $0;                    # exec self with new env
    ## NOT_REACHED
  }
}

This approach works in cases where the modules one is 'use'ing have their own initialization inside BEGIN blocks.

Edit: You also should make certain that this BEGIN block preceeds any uses or requires which may bring in such modules.
