/compat/linux/usr/bin/ldd always reports "not a dynamic executable"

[Kostas Oikonomou]

I am on FreeBSD 9.1, and I'm trying to use /compat/linux/usr/bin/ldd to 
tell me what libraries are needed by libpython2.7.so, a library obtained 
from a linux system.  But all I get is "not a dynamic executable".

In fact, the same thing happens if I run this ldd on a library in 
/compat/linux/lib:

[ko at wiley /compat/linux/lib]$ /compat/linux/usr/bin/ldd -v libc-2.9.so
     not a dynamic executable
[ko at wiley /compat/linux/lib]$

What is going on?    Thanks for any help.
