[CLAM] help with clam installation

[Dani Boronat]

hello, I still having a problem with the clam installation. I download
the clam I unpacked it and I change the path to
/CLAM-0.6.1/build/srcdeps, then I type make and everything is correct.
The scrdeps binary file has created. But when i change the path to
/CLAM-0.6.1/build and I type autoconf the following message appear

 bash: autoconf: command not found

thank you.
