You recall correctly. That's the recommended and correct way to install
Python 2.6 on a recent machine, with one exception. You must compile it
with the option MACHDEP=linux2, otherwise sys.platform will contain the
string "linux3" [1]. You also must set LDFLAGS and some other flags
because Python 2.6 doesn't support multiarch systems. [2] It's all in my
blog.

My default settings are:

export arch=$(dpkg-architecture -qDEB_HOST_MULTIARCH)
export LDFLAGS="-L/usr/lib/$arch -L/lib/$arch"
export CFLAGS="-I/usr/include/$arch"
export CPPFLAGS="-I/usr/include/$arch"
./configure --enable-shared --enable-unicode=ucs4 --config-cache
make MACHDEP=linux2 -j3
sudo make altinstall
