I would be willing to bet my morning scone that the problem is not cron.
Cron runs under a different, and often more restrictive, environment than
your shell.  Cron might not know where that script is;  you need to tell it.

As Daniel said, change your target to contain absolute paths, like so:
Target[bmpcmali_error]: `/usr/bin/perl /path/to/bm_rssi_error.pl bmpcmali`
                                       ^^^^^^^^^ New stuff
