[daip] error installing aips on workstation

[Pedro Manuel Augusto]

Hi Eric,

I am finally trying to install AIPS on our Sun-Sparc Ultra workstation
operating on SOlaris 2.7 (or 2.6? if relevant I will find out). I have
come across the error:

AipsWiz:  =====> Configuring READLINE library...

Is it because there is no program "autoconf" in the workstation? I have
searched for it and, indeed, I cannot find it. Do you know where I can
download it from?

Thanks for your help.

Pedro
