I get this:
capget(0x20080522, 0, NULL) = 0
getxattr("/usr/libexec/pt_chown", "security.capability", 0xbf9444ac, 20) = -1
EOPNOTSUPP (Operation not supported)
write(2, "Failed to get capabilities of fi"..., 85Failed to get capabilities of
file `/usr/libexec/pt_chown' (Operation not supported)
) = 85
Full output below.
