Hello,

please add "libcrypt-dev" to Build-Depends. Presently, libcrypt-dev is
transitively build-essential, because libc6-dev depends on it. There is an
effort[1] to drop this dependency with the result of removing libcrypt-dev from
the build-essential package set. This package was identified as needing an
explicit dependency on libcrypt-dev for one or more of several reasons:
 * It failed building in an archive-rebuild with the dependency dropped.
 * One of its binary packages issues a binary package dependency on libcrypt1.
 * Inspection of source identified "#include <crypt.h>" or -lcrypt.

Rarely, the dependency is of indirect nature. The most common cae is perl
extension modules. For those, a different bug has been filed requesting a
perl-xs-dev dependency instead. As other classes have been excluded from this
filing, it is expected that a direct "Build-Depnds: libcrypt-dev" is indeed
necessary.  Once the libcrypt-dev dependency issued by libc6-dev is dropped,
this package will fail to build or build with its crypt-related functionality
disabled. This change will not happen in the trixie cycle but some months into
the forky cycle. Please add the additional dependency in time. Whilst the
additional dependency is safe for inclusion in trixie, it should be added in
the forky cycle to avoid disrupting the trixie release.

Thank you

Helmut
