To be clear, I wasn't referencing ability when I wrote that, it was more
of a time efficiency comment. Obviously it's possible. :)
As I understand the ports system, ports are not generally created with
the idea of cross-compilation. Thus, I posit that it's best (lacking
fancier hardware) in terms of time spent and port build integrity to run
an emulator and do my port builds in a clean environment.
I could be very wrong here. QEMU may accomplish the goal of a compiled
ARM port, but what other requirement am I missing?

It is certainly appearing to be a struggle. I'm using virtualbox to run
a machine which runs QEMU, that might actually be my problem. However,
I'm under the impression that *this* struggle is much more likely to not
affect the integrity of a ports build.
