Intalação do LDAP

Estou utilizando os seguintes comandos:

#export CPPFLAGS="-I/usr/local/BerkeleyDB.4.5/include/ -I/usr/local/openssl/include/openssl/" LDFLAGS="-L/usr/local/BerkeleyDB.4.5/lib/ -L/usr/local/openssl/lib/" LD_LIBRARY_PATH=/usr/local/BerkeleyDB.4.5/lib/

# ./configure --prefix=/usr/local/ldap --enable-syslog --enable-bdb --enable-slurpd --with-tls

ERRO:
.
.
.
checking openssl/ssl.h usability... no
checking openssl/ssl.h presence... no
checking for openssl/ssl.h... no
configure: error: Could not locate TLS/SSL package

Esta dando este erro, alguém sabe como resolve-lo?

ESTE ERRO JA ARRUMEI.... Agora tenho que arrumar este que esta ai em cima!!!

Utilizei este comando :
#export CPPFLAGS="-I/usr/local/BerkeleyDB.4.5/include/ -I/usr/local/openssl/include/" LDFLAGS="-L/usr/local/BerkeleyDB.4.5/lib/ -L/usr/local/openssl/lib/" LD_LIBRARY_PATH=/usr/local/BerkeleyDB.4.5/lib/

Agora Preciso limpar esse variavel "CPPFLAGS" alguém te ideia de como fazer isso ?
Desculpe pela formatação do texto e que so deixou postar assim.
valeu!!!!!
