Comment (by dorfman at est.org):

 Sorry, I was traveling when the last response came in, and lost track of
 it by the time I got back.

 Although the rebuild command given didn't work due to complications
 relating from further efforts on my part to solve the problem, I was able
 to completely remove zlib and reinstall it from scratch. I did run the
 selfupdate first, and it indicated no changes were needed.

 After manually installing zlib the original command from the beginning of
 this ticked now works. It seems to me there must still be a bug somewhere,
 but my system no longer reproduces it.

 Also, I should mention that since I originally opened this ticket, I have
 upgraded to Leopard. It may be that the problem is 10.4 specific.
