No, this has been fixed since then.

Of course they are - if I install perl I cannot build xs-modules, I need
libperl-dev, and since perl requires linking against -lgdbm (or did so in the
past), *something* has to depend on libgdbm-dev, and the obvious place for
this is libperl-dev. The same is true for any other library perl is required
to link against when building your own perl binaries or modules.

No, back then, -lgdbm was in the set of libraries required for linking in
Config.pm, right now (5.10.1-14), it's only -lpthread.

Same princpiple applies - there must be a debian package which depends on
pthread.h and other development files because without it, building perl
modules isn't possible.

That doesn't need to be libperl-dev, but it would be the logical place for
that. I don't currently see the dependency anywhere (but I didn't look very
hard).

Without the dependency there is no way to build perl
extensions/binaries/modules without manually installing perl-dev
dependencies (currently only libc-dev).

Or maybe debian doesn't support ExtUtils::MakeMaker? Or maybe debian requires
one to install build-dependencies for perl to install modules?

All possible, and if true, just ignore/close this bugreport, and sorry for
the noise in that case (or actually, good that the original bug has been
fixed by now).
