[hylafax-users] Error during installation Hyalafax 5.2.7

[FOO SOON LOKE <fsloke@xxxxxxxxx>]

I am Ubuntu user. I setting setup a HylaFAx 5.2.7 [ latest version] server using the deb package from
http://osx.freshmeat.net/projects/hylafax/?branch_id=4243&release_id=282735
hylafax_5.2.7-1_i386.deb

Then I install as usual:
===========================================================================
Should I run faxmodem for each configured modem [yes]?
/usr/sbin/faxmodem ttyS0

Done verifying system setup.
henry@henry-desktop:~$ sudo /etc/init.d/hylafax restart
Stopping HylaFAX Servers.
HylaFAX:/usr/sbin/faxq: error while loading shared libraries: libldap_r.so.2: cannot open shared object file: No such file or directory
 faxq/usr/sbin/hfaxd: error while loading shared libraries: libldap_r.so.2: cannot open shared object file: No such file or directory
 hfaxd (without SNPP support).

When I restart the hylaFAx it prompt me an error as above....

May I know it the error will effect my installation?

Thank
