use Module::Load;
eval {

If you don't need to use Perl to do this, you could do this in a shell script:

#!/bin/sh
MODULES="Data::Dumper Foobar::Test"

for i in $MODULES ; do
  if $(perl -M$i -e '1;' >/dev/null 2>&1 ); do
    echo "Ok."
  else
    echo "No." 
  fi
done

You could do something else other than using echo.

The code sequence:

perl -MData::Dumper '1;'

will exit with an error value of 0 (ok) and

perl -MFoobar::Test '1;'

will exit with an error value of 2 (error occurred).
