[hsflinux] Winmodem for RedHat 9

[J Taylor]

I am new to Linux (started two days ago) and I am having trouble getting my
Winmodem to function.  I am using RedHat 9, kernel 2.4.20-6, which does not
have a specific RPM.  I have tried both the generic RPM and the generic
source with the same results.  Here is the message that I receive.

[root at localhost Generic_RPM]# rpm -i
hsfmodem-6.03.00lnxt03091800free-1.i386.rpmwarning:
hsfmodem-6.03.00lnxt03091800free-1.i386.rpm: V3 DSA signature: NOKEY, key ID

        gcc is needed by hsfmodem-6.03.00lnxt03091800free-1

Any suggestions?
