Postgress 8 cant find "readline" and "zlib" on Debian Woody 3.0 r2 --help

[Siju George <sgeorge.ml@gmail.com>]

Hi all,

I am trying to install postgresql ver 8.0.1 on my Debian Woody 3.0 r2

While configuring I get the following error

configure: error: readline library not found
If you have readline already installed, see config.log for details on the
failure.  It is possible the compiler isn't looking in the proper directory.
Use --without-readline to disable readline support.

but the 

libreadline4 (4.2a-5) GNU readline and history libraries, run-time libraries.

is installed on my Debian as you can see

# apt-get install libreadline4
Reading Package Lists... Done
Building Dependency Tree... Done
Sorry, libreadline4 is already the newest version.
0 packages upgraded, 0 newly installed, 0 to remove and 0  not upgraded.
#

How can I fix this??

I donot want to configure postgress using the --without-readline  option

but if I do configure with the --without-readline option I get the error

configure: error: zlib library not found
If you have zlib already installed, see config.log for details on the
failure.  It is possible the compiler isn't looking in the proper directory.
Use --without-zlib to disable zlib support.

could someone pleae tell me how to fix these issues??

thankyou so much

kind regards

Siju
