PCL-812PG: unresolved symbol comedi_done

Mi linux box is a Redhat 7.3, with 2.4.18-3 kernel version. Trying to make
comedi-0.7.59 work after having tried comedi-0.7.68 what in principle
brought me fairly the same unresolved symbols problems, so I decided to
switch back to comedi-0.7.59 just to follow religiously the documentation.

I have a PCL-812PG installed on port 0x230, no interrupts enabled nor DMA
transfer (if it matters).

I've followed the INSTALL file instructions and everything seems to install
flawlessly until I issue 'insmod pcl812' command, what yields the following
output from stdout (or stderr):

[root_at_dynamica05 root]# insmod pcl812
/lib/modules/2.4.18-3comedi/misc/pcl812.o: unresolved symbol range_unknown

/lib/modules/2.4.18-3comedi/misc/pcl812.o:
Hint: You are trying to load a module without a GPL compatible license
      and it has unresolved symbols.  Contact the module supplier for
      assistance, only they can help you.

Even if I issue the same command but for comedi_parport module, it
complains again.

I was sneaking around the source code to wonder whether it has to do with
any symbol that was not reachable at compilation time or something. Issuing
a search for one symbol definition it shows this...

[root_at_dynamica05 comedi-0.7.59]# pwd

Any ideas so far?
