LinuxQuestions.org - Ver 2 Compiler With Ver 3. Kernel wat to do?

HI everyone

I am still trying to get my WINMODEM to be a LinModem, there is success with it and im following some instructions anyway had some issues of not having the source files but anyway:
here is the output of installing the things (Read: No idea)

-------------------------------------------------------------------
[root@cam pctel-0.9.6]# insmod pctel

Using /lib/modules/2.4.21-0.13mdk/misc/pctel.o

/lib/modules/2.4.21-0.13mdk/misc/pctel.o: The module you are trying to load (/lib/modules/2.4.21-0.13mdk/misc/pctel.o) is compiled with a gcc

version 2 compiler, while the kernel you are running is compiled with

a gcc version 3 compiler. This is known to not work.)
---------------------------------------------------------------------

Thats the output i was following these instructions:

Installation
------------
0) Unpack the tarball by typing "tar zxvf pctel-0.9.6.tar.gz"

1) Go into that directory by typing "cd pctel-0.9.6"

2) Find out what chipset you have in your board:

3) ./configure
Options:

--with-hal=hal
Select one of: pct789, cm8738, i8xx, sis, via686a

--with-kernel-includes=/path/to/my/kernel-sources/include
If you don't have your kernel sources at /usr/src/linux, specifiy
your includes

4) Compile the modules by typing "make"

5) If everything went fine, get root by typing "su"

7) Install the drivers by typing "make install"

8) You are now ready to use your modules.
Type "insmod pctel" and "insmod ptserial".

-----------------------------------------------------------------------

Success upto 7

Any ideas? Running Mandrake 9.1 with KDE

2.4.21-0.13mdk
