compiling cyrus-imap-2_2

[Danny Garcia Hernandez]

hello:

i have a linux redhat 7.3 with cyrus-sasl, right now i´m trying to compile
cyrus-imap-2_2 from de cvs source but configure script is getting some
errors.

1- first i have created the configure script

   /bin/sh/ ./SMakefile

2- running configure without params

  ./configure

  loading cache ./config.cache
  configure: error: can not run ./config.sub

config.sub is in the directory.

can anyone give me some idea about what´s happen?

thanks
danny
