I am subscribed to the list, although I do need to update my list aliases.

I have openssl installed on my SuSE system. The header files are in 
/usr/include/openssl. The compiled binary is in /usr/bin/openssl. The shared 
library files are in /usr/lib.

So how do I go about running configure? I thought it would find the openssl 
libraries by itself without any arguments, but I've tried:

--with-openssl=/usr/bin/openssl
--with-openssl=/usr/include/openssl
--with-openssl=/usr

... and none of these have produced a check_http that can check https sites. 
The new check_http executables don't recognize the -S option, nor does the -S 
option show up when I type ./check_http -h

Looking at the debug lines from make (blank lines inserted by me), it doesn't 
look like check_http is getting linked with the openssl headers, even though 
these headers are all in /usr/include/openssl:

checking for openssl... (cached) /usr/bin/openssl
checking for krb5.h... (cached) no
checking for krb5.h... no
checking for openssl/ssl.h... (cached) no
checking for openssl/x509.h... (cached) no
checking for openssl/rsa.h... (cached) no
checking for openssl/pem.h... (cached) no
checking for openssl/crypto.h... (cached) no
checking for openssl/err.h... (cached) no
checking for ssl.h... (cached) no
checking for x509.h... (cached) no
checking for rsa.h... (cached) no
checking for pem.h... (cached) no
checking for crypto.h... (cached) no
checking for err.h... (cached) no
checking for CRYPTO_lock in -lcrypto... (cached) yes

The actual compile lines from make don't show it attempting to link 
check_http.c with the openssl libraries:

gcc -DHAVE_CONFIG_H -I. -I. -I. -I. -I. -I. -I. -I. -I.. -I../lib

gcc  -g -O2 -L. -L/usr/bin/openssl/lib -o check_load  check_load.o utils.o 
../lib/libnagiosplug.a popen.o -lutil

Any additional suggestions?
