Josh was trying to help. If you'd like to provide a patch to the configure
script to make it more robust in detecting the shared object libraries,
that would be appreciated. However, as Asterisk is installed on a wide
variety of platforms, such solutions are often very difficult to craft
correctly.

The configure script currently uses the AST_PKG_CONFIG_CHECK macro to
verify pjproject is installed. That will use the output of pkg-config to
verify whether or not the shared object libraries are installed. If, for
whatever reason, that returns success, then I would expect chan_pjsip to
enabled.

The config.log would illustrate why it returned success in your case.

That isn't what Josh said. pjproject is not a required external dependency.
You can run Asterisk just fine without it.

As for the suggestion of adding an INSTALL file: this is really just the
same as a README. Personally, we've found that the wiki provides a good
place to collect that information. Major items are still listed in the
README; as pjproject is not required for Asterisk, I'm not sure it has to
be there.
