First of all, there is a known bug in ldconfig which makes it produce
different output if you specify the lib with a path or not. E.g.,

$ /sbin/ldconfig -l -D ld-linux.so.1
/sbin/ldconfig: version 1.9.6
        ld-linux.so.1 => ld-linux.so.1 (SKIPPED)
$ /sbin/ldconfig -l -D ./ld-linux.so.1
/sbin/ldconfig: version 1.9.6
        ld-linux.so.1 => ld-linux.so.1

(Lintian always specifies the path to work around this problem.)

For the old python-base 1.4 package, for example:

$ cat ldconfig-info
usr/lib/python1.4/sharedmodules/arraymodule.so:
/sbin/ldconfig: version 1.9.6
/sbin/ldconfig: usr/lib/python1.4/sharedmodules/arraymodule.so is not a
shared library

I'm still unsure how to interpret this message. Is this intended to be a
shared libary? And what does the message mean actually (i.e., can the lib
be used for dynamical linking)? 

Any comments from the ldconfig experts are appreciated!

> b) I guess the fatal error is a bug in lintian.

Right. I've already change lintian behaviour to not abort completely, but
to skip the package. I'll improve this even more if I know what the
message exactly means.

Thanks for telling me! 


Thanks,
