IMHO, for direct dependency, explicit declaration is required (ex:
USE_GETTEXT=yes).
For indirect dependency, PORTVERSION bump is enough when shared
library version changes.
It is impractial to add all knobs which cover all combinations of
indirect dependencies.
If one of the dependencies requires gettext, gettext is already in the
depends list.
'make all-depends-list' shows the list.
Adding USE_GETTEXT to Makefile is needless.
Even more, it complicates and misleads the port dependency.
Think about A ---> B ---> gettext.
Say that you add USE_GETTEXT to A's Makefile.
Once B removes gettext from its dependencies (e.g. a newer version),
both A and B are gettext-safe now.
However, you still need gettext to build A due to the incorrect USE_GETTEXT.

Back to the libxslt case, I must emphasize that libxslt itself is gettext-safe.
It requires gettext if and only if libgpg-error was built with gettext.

At last, I do not see any serious breakages you mentioned.
Would you please give out some examples?
