binaries linking errors

[Wu Degang]

Hi,

After a upgrade outdated operation, I got the following messages in the end:

--->  Scanning binaries for linking errors: 39.9%
Warning: Error parsing file 
/opt/local/lib/apple-gcc40/lib/gcc/i686-apple-darwin11.3.0/4.0.1/kext/crt3.o: 
Premature end of data, possibly corrupt file
--->  Scanning binaries for linking errors: 39.9%

Premature end of data, possibly corrupt file
--->  Scanning binaries for linking errors: 100.0%
--->  No broken files found.

How should I interpret them? Do I need to worry about them? What should 
I do with them?

Thank you!
