problem configuring ifort

[renato vacondio]

I tried to configure ifort in kdevelop but I can't manage it.
I've done exaclty what is reported in: 
http://www.kdevelop.org/mediawiki/index.php/How_to_use_Intel_fortran_compiler 

but when i run automake & friends this is the output:

cd '/home/renato/Scrivania/pippo3' && WANT_AUTOCONF_2_5="1" 
WANT_AUTOMAKE_1_6="1" make -f Makefile.cvs && cd 
'/home/renato/Scrivania/pippo3' && F77=ifort 
"/home/renato/Scrivania/pippo3/configure" && cd 
'/home/renato/Scrivania/pippo3' && WANT_AUTOCONF_2_5="1" 
WANT_AUTOMAKE_1_6="1" make -k clean
aclocal
autoheader
automake
src/Makefile.am: Fortran 77 source seen but `F77' is undefined
src/Makefile.am: The usual way to define `F77' is to add `AC_PROG_F77'
src/Makefile.am: to `configure.in' and run `autoconf' again.
make: *** [all] Error 1

I'm running kdevelop under ubuntu 7.10.

Thank you for your help, because I'm quite new to linux.
