Thanks casevh for your time & patience.
The ./configure . . .  was a "continuous" line , although it ran over to
next line even on 132 char wide terminal because of names of system &
dir.  I was careful with the spaces and hyphens.
In my reply the "make install" was a typo , I did run  make altinstall.

Moved all my code to pycode dir on my home directory.  Removed all
files from /usr/local/lib/python3.1/dlmodules and removed that dir. 

Twice ran the recompile :
    make distclean
    ./configure --prefix=/usr/local --with-computed-gotos
            --with-wide-unicode
        <^ one space>
    make
    sudo make altinstall 
After each reinstall had same problems :  cannot import  random  or
any code using it, although random.py is in Lib :
    Traceback
        File "<stdin>", line 1, in <module>
        File "random.py", line 46, in <module>
            import collections as _collections
        File "collections.py", line 9 in <module>
            from _collections import deque, default dict
    ImportError: /usr/local/lib/python3.1/lib-dynload/collections.so:
        undefined symbol: PyUnicodeUCS4_FromString

After second reinstall today I also found that a module importing
    "time"  would not run.  Likewise could not import  time  at  >>> .
Same error, ending : undefined symbol: PyUnicode UCS4_FromString

And my original problem still there : fouled up keys in interactive
terminal. Seems minor now ; )   Should I try to remove everything
and reopen the tarball ?
