PostgreSQL version: 8.4.6
Operating system: Linux / Debian Lenny 5.0.6
Description: configure script does not check for perl devel files
Details:

to build postgresql from source on debian lenny you need to install the
following packages:

apt-get install bison flex libreadline5-dev zlib1g-dev libssl-dev
libxml2-dev libxslt1-dev

in order to run ./configure without any errors.

However, during the make, postgres requires perl devel. Should this not be
covered in the configure script?
