Mac OSX update killed MySQL

Question

On a G5 Mac OSX 10.4.7, build 8J135 dual 2GHz Power PC with MySQL versions; mysql-standard-4.1.18-apple-darwin8.2.0-powerpc-64bit
mysql-standard-5.0.24-osx10.4-powerpc-64bit
The first one (4.1.18) has been running for some months and working fine with open office org to generate merge mail. I seem to recall did a Mac OSX system update from apple between the last time I used it. When I tried to use MySQL for first time in a week got "segmentation error" on login to MySQL. Discovered the daemon was not running. It wouldn't start. Tried to install the new version to see if that would help with new OSX updates. Nope, it won't start either. When I run the new version as test this is what i get;
Logging: ./mysql-test-run

Anyone have any clues as to what I should try next? Thanks.

I don't know the first word about MySQL, but when porting
my own program to 64-bits I kept getting 'Illegal Instruction' faults.
Does MySQL install its own signal handlers using 'sigaction'?
If so (and this was the problem with my proogram), I found
the following note useful. That problem went away after
I added the SA_64REGSET flag in the call to sigaction.
This is obviously a work-around as sigaction should operate
properly when called from 64-bit programs, but be that
as it may...
