installing autoconf ? ? <how?>

  1. Set up your environment by installing the following software:

autoconf, automake, bison, flex, gcc, make, ncurses, patch, readline, subversion, texinfo, wget

i have installed cygwin in my pc and downloaded the PSP toolchain

now , how can i make this command run
Due to a recent problem with the toolchain, we need to update everything, so to get the updates and have them modify the toolchain script, you will need to type “svn update” and hit enter.

:o
it doesn’t run !

when i say
./toolchain.sh
it says

install autoconf before continuing

that is about to drive me crazy :mad:

have i to dance on the coconuts song for you to help me ??? please help

Never mind, I should read before posting :o
