[maemo-developers] different binaries for the same version?

[From: Thomas Tanner]

Hello,

I just tried to install liblzo2-2, but I got the following error (with
fresh apt-get update):

The following NEW packages will be installed:
  liblzo2-2
0 upgraded, 1 newly installed, 0 to remove and 8 not upgraded.
Need to get 56,1kB of archives.
After this operation, 193kB of additional disk space will be used.

 Size mismatch
E: Unable to fetch some archives, maybe run apt-get update or try with
--fix-missing?

the package in

http://repository.maemo.org/pool/fremantle/free/l/lzo2/

has indeed a different size than the ones in

http://repository.maemo.org/extras/pool/fremantle/free/l/lzo2/
http://repository.maemo.org/extras-testing/pool/fremantle/free/l/lzo2/
http://repository.maemo.org/extras-devel/pool/fremantle/free/l/lzo2/

How is this possible?

Was the package recompiled and but the version number not changed?

If someone uploads the same source, just to recompile it against
the latest SDK or dependencies, wouldn't it be a good idea to increase
the version number?

best,
