$ ./configure --prefix=/usr/local --enable-debug && make

This should do the installation - depending on your prefix location,
you might to run this as root:

$ make install

Then let your LD_LIBRARY_PATH point to your modified lib and read
http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html for
more information.
Or just use the binary Ubuntu packages and be done.

I'd rather put it that way: If it was a bug in the alsa lib that is so
easy to trigger, you wouldn't be the first one to discover it :)
