Hi again,

first thanks a lot for your answer. Things work exactly as you said - in 3.0.2, but not in 3.0.3.

The file already contains the correct parameters - even without the parameter CPPFLAGS="-I /opt/openssl/include" for the configuration script:
> CPPFLAGS        =     -isystem /opt/openssl/include
If you pass CPPFLAGS="-I /opt/openssl/include" to the configure script, you get the path twice:
> CPPFLAGS        =     -isystem /opt/openssl/include   -I /opt/openssl/include

However, in both cases make fails compiling the module rlm_always because the
system can not find openssl/err.h and other openssl header files. Is it
possible that there are system openssl header files on your machine, maybe in
/usr/local/include or in /opt/include, which the preprocessor uses? I am sure that such files do not exist on my machine. Could this be the rason why make runs well on your system, but not on my machine?

Best regards,
