Hello, sorry to bother again, I've made up my mind and will install everything, including apache2 from the package distributions, as I've looked inside the files they come with and see that there is very little I will get with the configuration on my own. There's tons of packages to add curl, imap, php with mysql and so and so. However, this will seem ridiculous, since I've already had installed the IMAP toolkit in my previous mail. But I deleted the whole folder thinking I would make a fresh start. Now, I have the original folder that I have uncompressed again. But I keep getting the error related to the signing utility x509v3.h that I commented before, so once again I have to annoy you with my questions: How do I get the signing utility to work with the packages I already have. I must note that I made apt-cache on libpam-dev and libssl-dev and they are both installed, I can't even reinstalled them as the result of apt-get install is that I have the most recent versions. I wonder what's going on with that hallowed signing utility. It's worth noticing that such x509v1 to 3 is what went wrong with the tests installing openssl from source, but that shouldn't matter, as I did sudo rm -rf on the whole openssl folder and I noticed I have the shared libraries of openssl and the binaries in usr/bin/openssl as expected. Thanks for your help.
