Easier to use system.
system("/usr/bin/make -f ./Makefile") == 0 or die "make failed!";
If you need the error, you could capture STDERR.
From perlfaq8:
To capture a command's STDERR but discard its STDOUT:
$output = `cmd 2>&1 1>/dev/null`; # either with backticks
$pid = open(PH, "cmd 2>&1 1>/dev/null |"); # or with an open pipe
while (<PH>) { } # plus a read
open COMMAND with a pipe
