Description: mysql database client library
MySQL is a fast, stable and true multi-user, multi-threaded SQL database
server. SQL (Structured Query Language) is the most popular database query
language in the world. The main goals of MySQL are speed, robustness and
ease of use.
.
This package includes the client library.
Provides: libmysqlclient15off

But when I try to install a package which depends on
libmysqlclient15off, I get error like this:

server01-vz16:~/packages/mysql/5.0/work/mysql-dfsg-5.0-5.0.32# apt-get

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
libdbd-mysql-perl: Depends: libmysqlclient15off (>= 5.0.24-2)
E: Broken packages

What am I doing wrong?

Nothing, basically. The bad news is that dpkg does currently not allow
versioned `Provides'; see http://bugs.debian.org/24934 and its
relatives. Until that is resolved¹, you're simply out of luck. :-(

PS: Sorry for my English.

No need for that, your English seems OK to me (though I'm not a native
speaker myself).

PPS: Changing just the version number of the package and leave it's name
is not an option now.

Then you probably have to implement versioned `Provides' in dpkg.

¹ Given that the bug is only at `wishlist' severity and dpkg has a
plethora of other open bugs, this will probably not happen any time
soon, if at all.
