They are using the exactly same names. See following for more information:

# The self-compiled curl git master version:
$ realpath -e /usr/local/lib/libcurl.so.4
/usr/local/lib/libcurl.so.4.6.0

# The curl installed from distro's repo:
$ realpath -e /usr/lib/x86_64-linux-gnu/libcurl.so.4
/usr/lib/x86_64-linux-gnu/libcurl.so.4.6.0

Do you mean using the debuild tool to build the deb package for it?

I've been using this method for very long time, and it does work smoothly.

For the case where the packages dependencies problem cannot be solved
by using the ones shipped by the distro's repo.
