Imapd-2.1.15 configure error - newbie help

[sean_berry at cox.net]

I am trying to ./configure cyrus and it tells me at the end...

 configure: error: Cannot continue without libsasl2.
 Get it from ftp://ftp.andrew.com.edu/pub/cyrus-mail/.

 But I have gone there and there is nothing that I can find to help.

 Any suggestions.

 This is for imapd-2.1.15



 ALSO, if anyone know of or has any good documentation of installaing and
 configuring cyrus, I would really appreciate it.
