Problems compiling nessus 2.0 on Solaris.

[Jesse W. Asher]

I'm trying to get nessus 2.0 compiled on Solaris 9 and I'm having a 
problem.  I'm not sure what is causing it, but bison appears not to be 
producing a needed file.  Here is the error:

make[1]: Entering directory 
`/export/home/jasher/src/nessus-2.0/libnasl/nasl'
bison  -d -v -t -p nasl nasl_grammar.y
/bin/sh /export/home/jasher/src/nessus-2.0/libnasl/libtool --silent gcc 
-pipe -g -O2  `sh ./cflags` -c nasl_grammar.tab.c
gcc: nasl_grammar.tab.c: No such file or directory
gcc: no input files
make[1]: *** [nasl_grammar.tab.o] Error 1
make[1]: Leaving directory `/export/home/jasher/src/nessus-2.0/libnasl/nasl'
make: *** [all] Error 2

The bison version # is 1.5.  I've run bison by hand in various 
permutations with no luck.  Anyone have any ideas as to what could be 
causing this?  Thanks!!
