On my laptop, which I guess is 64-bit capable, I installed FPC 3.0.0
by copying the port from 5.9 ports, then installed Lazarus 1.6
directly from the tarball, no problem at all. Might be a 32/64 bit
thing, this is an old Dell Optiplex GX270 from 2002. Both under
OpenBSD 5.7. A few differences in other installed software between
the 2 machines but not many.
