If you want to use a shell variable here, you need to modify the code to
use double quotes rather than single quotes.

    [AS_IF(["$PERL" -e 'require $1;' >/dev/null 2>&1],

That would need to be "require $1;" instead.  Also, the shell variable
would need to be exported.

It would be easier to not use shell variables.
