Can't read" messages when run "./configure"?

Hi,

I have download latest openldap at
ftp://ftp.OpenLDAP.org/pub/OpenLDAP/openldap-stable/openldap-stable-20020215.tgz

When I run "./configure", there are some "can't read" messages as following:
--------------------------Begin my logs-------------------------------------

Are there any problem?
I attached also "configure.out" that is the result of running "./configure"
on my computer.

Thach!
