[pptp-server] Unresolved Symbols

[Trivial-pursuit]

I have been working at getting pptp working, and have read multiple lists
and docs and got to this point:

insmod ppp_mppe.o
ppp_mppe.o: unresolved symbol __floatsidf
ppp_mppe.o: unresolved symbol __adddf3

I have done this 
from /lib/modules/2.2.18/net/ 
and 
from /usr/src/linux/drivers/net

PPP:                                   PPP-2.4.0
Poptop:                                pptp-1.0.1
kernel:                                linux-2.2.18
cpu:                                   TI UltraSparc IIi 
sparc64-linux-gcc.egcs64 --version:    egcs-2.92.11
ppp-2.4.0-openssl-0.9.6-mppe.patch.gz installed
all the rc4 files are in /usr/src/linux/drivers/net

Any clues?
