.for evaluates its arguments immediately, not delayed. _MANPAGES is defined in
bsd.port.pre.mk, so it is only defined *afterwards*. Works as advertised.

**Be aware that nobody guarantees you that _MANPAGES is available after bsd.port.pre.mk**
Changes in bsd.port.mk may break your code without further notice.
