Urgent: Unable to successfully compile slapd for OpenLDAP 1.2.11 in RedHat Linux 7.1

[<ywshum@maxis.net.my>]

Hi everyone, 
We're trying to install openldap 1.2.11 into RedHat Linux 7.1 . 
We did the following: 
/configure --enable-shared --enable-static 
make depend 
make 
make install 
We discover the "slapd" is not built at all. In fact, after the "make" step, we 
saw the following messages on the screen 
amount the other messages: 


make[5]: Entering directory `/home/mailusers/install/openldap-
1.2.11/servers/slapd'

make[5]: *** No rule to make target `.backend', needed by `libbackends.a'. 
Stop.

make[5]: Leaving directory `/home/mailusers/install/openldap-
1.2.11/servers/slapd'

make[4]: *** [backendslib] Error 2

make[4]: Leaving directory `/home/mailusers/install/openldap-

make[3]: *** [all-local-srv] Error 2

make[3]: Leaving directory `/home/mailusers/install/openldap-

make[2]: *** [all-common] Error 2

make[2]: Leaving directory `/home/mailusers/install/openldap-
1.2.11/servers/slapd' 
Consequently, slapd is not built. 
All this while we have tried in RedHat linux 6.2 and there's no problem. 
What's causing the make to fail? Please help. 

regards 
paris
