netpbm at 10.81.01+universal+x11 build failed on Snow Leopard

[Richard L. Hamilton]

Looks like at least the immediate problem (not to say there might not be others) is that strnlen() is missing on Snow Leopard.

When this came up for something else before, some magic known as snowleopard_fixes took care of it, according to old email.  I gather that supplies the functions missing on Snow Leopard that are relatively straightforward to re-create and have been helpful getting ports to build there.

How might that magic be added to the Portfile for netpbm?  Ticket #55716 filed.
