This is more a development question, so curl-library is a better place to ask.

The path given to the --with-ssl option might be confusing the build system, as
it's also finding pkg-config. You could try it again dropping the
/usr/local/ssl and making sure the PKG_CONFIG_PATH variable is set correctly
instead (as documented in docs/INSTALL).

Are these the correct locations?

It's not clear whether the line breaks are supposed to be in this log, but are
there libcrypto.so and libssl.so files in that last directory? Are they
pointing to the right locations? Are there .la files in that directory and are
they correct?
