    When you compile python2.6 with --prefix=/opt/python2.6, the binaries will be installed at /opt/python2.6/bin, the libraries at /opt/python2.6/lib, ...

    /opt/python2.6/bin/python: error while loading shared libraries: libpython2.6.so.1.0: cannot open shared object file: No such file or directory

    This error means that python is not looking at the path the file is in. So you need to add the library path to /etc/ld.so.conf file and activate it with ldconfig:

    # echo "/opt/python2.6/lib" > /etc/ld.so.conf.d/libpython2.6.conf
# ldconfig

  2. in Step 2 try add LDFLAGS with right path... for example

    env LDFLAGS="-L/opt/python2.6/lib -R/opt/python2.6/lib" ./configure --prefix=/opt/python2.6 --with-threads --enable-shared
