Is there theoretical problem to make dual-brand binaries ?
real situation: I need FreeBSD program with linux libraries
It seems it need to load some kind of universal loader ... I don't know
perl loads (!) linux and freebsd libraries but makes core while linking
# ldconfig -m /compat/linux/lib
# ldconfig -m /compat/linux/usr/lib
# perl
use DBD::Oracle;
^D
Bus error (core dumped)
# gdb -c perl.core /usr/bin/perl
