New install of 1.5.10 replacing 1.5.6: many things not working

[Joe Landman <landman at scalableinformatics dot com>]

Hi folks:

 I have multiple machines with 1.5.6 installed.  I wanted to upgrade to 
1.5.10 (bug fixes, speed, etc).  Stuff worked (for the most part) in 
1.5.6. I was/am looking to using it for application development on windows.

 With 1.5.10 install, I get error messages about find.exe being given 
bad arguments.  Many of the post-install scripts die with problems with 
grep (more in a moment).  When I open the cygbash shell, it puts me into 
/usr/bin by default, and the moment I cd out of there, I lose any 
ability to run basic commands such as ls.  Anything that tries to use 
grep is rewarded with an error message about /bin/grep not existing.  
Quick ls'ing around (find does not work... sigh) does not locate a grep.

 Ok, I may be thick, but I think that there might be a problem here. 

 The machines with problems:

1) Windows XP Home laptop.  SP1 installed.   512 MB ram

2) Windows 2000 desktop.  SP_something_or_other installed.  768 MB ram

Both had similar working copies of 1.5.6 installed.  Starting up the 
cygbash shell resulted in being in the /home/landman directory (where I 
thought I should be).  Everything properly pathed out in the older version.

Any thoughts?  I don't have to re-install the OS... (I hope :( ).

Thanks.

Joe
