unzip: problems with architectures and ld

Hi all.
I have a custom MacPorts installation in /opt/macports-i386.
Apart from the location, the only non-default option in macports.conf
is 'build_arch i386'.
Trying to install unzip I get a bunch of warnings like

ld: warning: in unzip.o, file was built for i386 which is not the
architecture being linked (x86_64)

and the following error

Undefined symbols:
  "_main", referenced from:
      start in crt1.10.6.o
ld: symbol(s) not found

This happens both with and without trace mode.
Please find attached the main.log of `sudo /opt/macports-i386/bin/port
-t install unzip`.

How can this be solved?

Best wishes.
