Another ISPConfig install error

Installed a fresh system as per setup guide for suse 10 and I got this when installing ispconfig

Configuring extensions
checking whether to enable LIBXML support... no
checking libxml2 install dir... no
checking for OpenSSL support... yes
checking for Kerberos support... no
checking for pkg-config... no
configure: error: Cannot find OpenSSL's <evp.h>
ERROR: Could not configure PHP
T1-01:/tmp/Downloads/install_ispconfig #

Any ideas??

 

Is it a 64-bit system, or 32-bit?

 

Sorry all fixed... the fixes I applied the last time I had this probelm did not work so I hunted around and found some more that did. Thanks for your reply
