Subject: missing bison, gperf not detected, do I need ruby to build ruby?

Hi,

It seems ./configure did not detect the fact that bison was missing from
my machine:


svn co http://svn.ruby-lang.org/repos/ruby/trunk ruby
cd ruby
autoconf
./configure
...
make
/bin/sh: gperf: not found
...
gcc -g -O2  -I. -I.ext/include/i686-linux -I./include -I.
-DRUBY_EXPORT  -c numeric.c
gcc -g -O2  -I. -I.ext/include/i686-linux -I./include -I.
-DRUBY_EXPORT  -c object.c
gcc -g -O2  -I. -I.ext/include/i686-linux -I./include -I.
-DRUBY_EXPORT  -c pack.c
bison  -o parse.c parse.y
make: bison: Command not found
make: *** [parse.c] Error 127

=========================
sudo aptitude install bison
sudo aptitude install gperf
=========================
make

...
gcc -g -O2  -I. -I.ext/include/i686-linux -I./include -I.
-DRUBY_EXPORT  -c version.c
gcc -g -O2  -I. -I.ext/include/i686-linux -I./include -I.
-DRUBY_EXPORT  -c blockinlining.c
rm -f ruby
ruby ./tool/insns2vm.rb --srcdir="."
/bin/sh: ruby: not found
make: *** [optinsn.inc] Error 127


What? Do I need an installed ruby to build ruby from trunk or am I
missing something else here?
If I need ruby, shouldn't configure complain that I don't have it?

SVN currrently at r12933
Using Ubuntu 7.04
