Right, when it's just TOOL_DEPENDS or USE_TOOLS (without :run), pkgsrc
will build the native package it needs. What I think gdt meant is
that, while you can't cross-compile Perl, you can do something like
# Natively compile just Perl on the slow evbarm board.
ssh targethost 'cd /usr/pkgsrc/lang/perl5 && make package'
# Make it available as a cross-package on the fast build host.
ssh targethost 'cd /usr/pkgsrc/packages && tar cf - All/perl5-*.tgz' | (cd /usr/pkgsrc/packages.evbarm && tar xvf -)
# Cross-compile anything that depends on Perl on the fast build host.
cd /usr/pkgsrc/net/samba && make package
If you do that, then you can make progress cross-compiling any package
that depends on Perl, but it's a manual step; of course, you can also
get rid of the Perl dependency and avoid the manual step, but it
requires changes package-by-package.
(Obviously it would be better if Someone^TM taught pkgsrc to do this
automatically in qemu-user-arm or something.)
