trouble building ncftp-3.0.2 from source

[Cristian Ionescu-Idbohrn <cristian.ionescu-idbohrn@axis.com>]

I'm having a hell of a time :( building ncftp-3.0.2 from the source
package. I get these errors and can't figure out the error source.

Many of these "undefined references" are in spool.[ch] and cmds.c
includes spool.h. At least some of them should not make my life
miserable.

All this started because I'm trying to build ncftp with libsocksd
(SOCKS library for dante-client), but that may be a dead end too.

Can anyone please point me in the right direction?
