Thanks for Mauro, Bernhard Reiter and Joerg Sommer for their help.
For the archives (if somebody has a similar problem), I chose to go
with the sysctl method, now my /etc/sysctl.conf has

# 3-button mouse emulation
# turn on emulation
/dev/mac_hid/mouse_button_emulation = 1
# Send middle mouse button signal with the F11 key
/dev/mac_hid/mouse_button2_keycode = 87
# Send right mouse button signal with the F12 key
/dev/mac_hid/mouse_button3_keycode = 88

which works nicely, assigning F11 and F12 to buttons 2 and 3.  The
keycodes produced by xev are different from the ones given by showkey,
and I had use the latter.  For some reason I thought this would require
gpm working, but apparently it does not because it is done by the
kernel.

Thanks,
