-During Configure, you may see the message
-
-*** WHOA THERE!!! ***
- The recommended value for \$d_msg on this machine was "undef"!
- Keep the recommended value? [y]
-
-as well as similar messages concerning \$d_sem and \$d_shm. Select the
-default answers: MachTen 4.1 appears to provide System V IPC support,
-but it is incomplete and buggy: perl should be built without it.
-
-Similarly, when you see
-
-*** WHOA THERE!!! ***
- The recommended value for \$d_vfork on this machine was "define"!
- Keep the recommended value? [y]
-
-select the default answer: vfork() works, and avoids expensive data
-copying.
-
-You may also see "WHOA THERE!!!" messages concerning \$d_endspent,
-\$d_getspent, \$d_getspnam and \$d_setspent. In all cases, select the
-default answer: MachTen's support for shadow password file access is
-incomplete, and should not be used.

At the end of Configure, you will see a harmless message
Hmm...You had some extra variables I don't know about...I'll try to keep 'em.
