Sure. But as I said (quote):

2. If you install a package from CPAN, then the maintainer is
responsible for it. That makes sense. So if you have issues with the
current version of a module from CPAN, then feel free to bug the
maintainer. If you have issues with an older version you get from
CPAN, then it's up to the upstream people whether or not they consider
your issue a bug, and whether they want to fix it.

You risk alienating the upstream this way, but it is your prerogative,
of course.

Here are the versions available in our package pool:

http://ftp.debian.org/debian/pool/main/libs/libsql-statement-perl/

Unfortunately, the oldest version we have is:
libsql-statement-perl 1.15-2

I tested this on my system (installing 1.15-2 doesn't work; I don't
think I have oldstable in my apt configuration)

> sudo apt-get install libsql-statement-perl=1.15-3
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following NEW packages will be installed:
  libsql-statement-perl
0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.
Need to get 128kB of archives.
After this operation, 438kB of additional disk space will be used.
Get:1 http://ftp.ca.debian.org stable/main libsql-statement-perl 1.15-3 [128kB]

You can always install older versions via CPAN manually too, and in
Debian's case at least, you can also recommend we provide that older
version for compatibility with things. I'm not sure of what other
resolutions we could have; maybe someone else can chime in.
