Before others jump on this...I have replied off list to this but I
might as well copy it to the list.
You should really do ldd from a unix escape in the Matlab console since
Matlab sets the LD_LIBRARY_PATH variable on startup. This is what I
have:
>> !printenv LD_LIBRARY_PATH
/usr/local/matlab5/sys/lnx86:/usr/local/matlab5/bin/lnx86:/usr/local/matlab5/ext
ern/lib/lnx86:/usr/local/matlab5/windu/lnx86:/usr/local/matlab5/opengl/lib/lnx86

I don't get a libreadline at all.
Matlab has a set of libraries that Matlab was compiled against at
ftp://ftp.mathworks.com/matlab/tech-support/library/linux/matlab5/ you
could get those and install them in $MATLAB/sys/lnx86 and see if that
helps. Here is my $MATLAB/sys/lnx86
