grx246 installation errors on mandrake 10.1

[Carlton Matthew]

I am attempting t install grx246 on my mandrake10.1 system, with no luck 
todate.
I have changed the optimisation levels from o2 to o1 to prevent the REG 
errors,
but now using
./configure --di-svgalib --enable-direct-mouse
make -f makefile.lnx
I get the errors:-
make[1]: Entering directory `/home/carlton/grx246/src'
gcc -o ../bin/modetest utilprog/modetest.o ../lib/unix/libgrx20.a  -lm
../lib/unix/libgrx20.a(vtable.o)(.data+0x0): undefined reference to 
`_GrVideoDriverSVGALIB'
collect2: ld returned 1 exit status
make[1]: *** [../bin/modetest] Error 1
make[1]: Leaving directory `/home/carlton/grx246/src'
make: *** [libs] Error 2

Using the --di-svgalib I assumed should disable svga options, so why the 
rederence to GrVideoDriversSVGAlib?????
any clues - I really need to get this up and running ASAP
TIA
Carlton
