Problem Solved. Thanks to KD, W5YR! The problem was that binary KVASD_g95 was not in a directory included in my $PATH. Here's what I did to verify and then fix the problem.
1. First I verified that $PATH environmental variable DID NOT include the directory where KVASD_g95 was located:
lj@lian2:~$ echo $PATH
lj@lian2:~$ locate KVASD_g95
2. So I put a copy of KVASD_95 in /usr/local/bin which IS in the $PATH:
lj@lian2:~$ ls -al /usr/local/bin
drwxr-xr-x 2 lj root 4096 2011-11-27 07:46 .
drwxr-xr-x 10 root root 4096 2010-04-29 06:17 ..
-rwxr-xr-x 1 lj lj 425598 2011-11-21 14:38 KVASD_g95
3. Then I verified that my copy KVASD_g95 was in a directory included in the $PATH variable;
lj@lian2:~$ whereis KVASD_g95
4. I also changed the ownership of the /usr/local/bin to my local user.:
lj@lian2:~$ sudo chown lj /usr/local/bin
5. Next I should determine why all my object code (*.o files) are dumped into the wsjt_code directory. Must be something wrong with the configure. I would expect that the output from the compilation would be dumped in a separate directory, say /usr/local/bin for example. Also it's odd that the WSJT binary wasn't found and read from the source code directory where all the other files are. Must be that KVASD_g95 is not invoked with ./KVASD_95
So the problem wasn't a 64bit vs 32 bit problem after all.
