Hi Roberto,
Thank you a lot for your advices.
I'm not familiar with signatures, but here is what I did (I tested that procedure on several other versions, but none worked...)
silvere@silvere-Linux:~/dev/
src$ wget
http://www.cs.unipr.it/~bagnara/pgp_public_key
silvere@silvere-Linux:~/dev/
src$ ls
MD5SUMS pgp_public_key ppl-0.11.2.tar.bz2 ppl-0.11.2.tar.bz2.sign ppl-0.11.2.tar.lzma
silvere@silvere-Linux:~/dev/
src$ gpg --import pgp_public_key
gpg: key B5944392: "Roberto Bagnara <bagnara@cs.unipr.it <mailto:bagnara@cs.unipr.it>>" not changed
gpg: Total number processed: 2

silvere@silvere-Linux:~/dev/src$ gpg --verify ppl-0.11.2.tar.bz2.sign ppl-0.11.2.tar.bz2

What do you think I did wrong ?
Nothing, as far as I can see. But please let me have also
the output of `ls -l' and (after downloading the MD5SUMS)
the result of `md5sum --check MD5SUMS'. Here is what I get:
$ wget -q ftp://ftp.cs.unipr.it/pub/ppl/releases/0.11.2/ppl-0.11.2.tar.bz2

I know it's not particularly a development issue, but I'm trying to
download ppl sources to compile a cross-compilation tool chain but
What ever the source I download from the ftp server, i'm not able to

Do you have any idea on how I could solve that issue ?
We need more details about what you observe. Here are the
result of a small experiment performed just a few minutes ago:

To reproduce the last step, please see

Of course, this only tested the bzip2 tarball. Which is the one
you found corrupted?
Have a nice day, and thank you for that software.
Thanks to you for the report.
Kind regards,
Roberto
