Your question is not really a Perl question and more a question of job control or a shell question. Personally, I would use a plain shell script instead of a makefile, as you have not explained how the two processes depend on each other and by what mechanism make would determine that it only needs to run the second step.

#!/bin/ksh
set -e

perl -I -Mmod1 -Mmod2 pgm.pl paramFile 
perl -I -Mmod3 -Mmod4 pgm2.pl paramFile2

The -e switch makes the shell script stop if any of the programs fails.
