[Koha-devel] Koha dev install

[Library Guy]

perl Makefile.PL creates a complete Makefile when run from the stable tar,
but if instead I choose a dev install from kohaclone after git pull,
the Makefile is
incomplete.  Hence my dev version of koha-httpd.conf contains only
variable names:

## OPAC
<VirtualHost __WEBSERVER_IP__:__WEBSERVER_PORT__>
   ServerAdmin  __WEBMASTER_EMAIL__
   DocumentRoot __OPAC_WWW_DIR__
   ServerName __WEBSERVER_HOST__
#  ServerAlias opac.mydomain.com
   ScriptAlias /cgi-bin/koha/ "__OPAC_CGI_DIR__/opac/"
   ScriptAlias /index.html "__OPAC_CGI_DIR__/opac/opac-main.pl"
   ScriptAlias /opac-search.pl "__OPAC_CGI_DIR__/opac/search"
   ScriptAlias /search "__OPAC_CGI_DIR__/opac/search"
   ErrorLog __LOG_DIR__/koha-opac-error_log
#  TransferLog __LOG_DIR__/koha-opac-access_log
   SetEnv KOHA_CONF "__KOHA_CONF_DIR__/koha-conf.xml"
   SetEnv PERL5LIB "__PERL_MODULE_DIR__"

What am I missing?

Thanks!
