Unluckily FreeBSD's shell isn't able to read from/write to /dev/stdin

and stdout.
Therefore we have to use bash as shell for /usr/local/bin/aps2file
program.
Arrange things with patch and pre-configure command, so that this
port stays prefix-clean.
The patch inserts !!PREFIX!!/bin/bash and configure configures in
the current PREFIX settings.
I'd whish somebody could fix our shell to remove the dependency from bash.
