I am against the idea.

Development package names could differ according to
distributions/OS. For example, the developement package of OpenSSL is
"openssl-dev", not "openssl-devel" in Debian or Debian derived
systems.

Another reason is, a user who is installaing software from source code
should be familiar enough with the fact that each software requires
development libraries.

In summary adding not-so-complete-list-of-development-package-names to
our document will give incorrect information to novice users, and will
be annoying for skilled users.

I don't think so. "libmemcached-devel" is just a package name in a
cetain Linux distribution. "libmemcached" is a more geneal and non
distribution dependent term.
