Unless the library you're talking about is part of MacPorts itself, it does not matter what architecture MacPorts itself is installed for.

Unfortunately the scite software does not use autoconf or cmake or Xcode or any other standard configuration system, so it does not support the build_arch setting of macports.conf out of the box, and nobody has modified the Portfile to retrofit this ability. You should file a bug report about this in the issue tracker.

No, there is no command you can run at the command line to fix this. The Portfile needs to be modified to support this.
