LilyPond for OS X: Intel download shows as PowerPC

[Brian]

I have downloaded several versions of LilyPond listed as being for Intel, but
they all have this problem:

1.  Computer identifies it as being a PowerPC app (Get Info)

2.  App is shown incorrectly as being created and modified on March 23, 2006
(Get Info).  All versions for OS X released after this date seem to show this
date.  This is mainly a problem when someone wants to identify the vintage of
the program (a common thing I do when troubleshooting a problematic app).

Versions of LilyPond for OS X Intel that I've checked for both of these issues
include:
2.11.28-1
2.11.22-1
2.10.25-2
2.8.8-1

Running OS X 10.4.10 on MacBook Pro

Thank you for all LilyPond contributers.
