[Help-gnu-radius] Make Errors

[Paul]

I'm trying to compile Radius 1.2, but I'm getting the following errors:

tsh.c: In function `tsh_readline_init':
tsh.c:438: `rl_getc_function' undeclared (first use in this function)
tsh.c:438: (Each undeclared identifier is reported only once
tsh.c:438: for each function it appears in.)
tsh.c: In function `tsh_command_completion':
tsh.c:512: warning: return makes pointer from integer without a cast
make[4]: *** [tsh.o] Error 1
make[4]: Leaving directory `/usr/local/src/radius-1.2/radiusd'
make[3]: *** [all-recursive] Error 1
make[3]: Leaving directory `/usr/local/src/radius-1.2/radiusd'

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/usr/local/src/radius-1.2'

Any feedback would be appreciated, even if you only point me back to the 
manual. ^_^
