>Description:
graphics/libchamplain fails to compile if an older version of the port
is installed and can no longer find libgcrypt.so.16, for instance, when
running portmaster -r libgcrypt. The latter gets updated to .so.17, but
the installed champlain-gtk library still relies on libgcrypt.so.16.

As workaround, the old libchamplain must be deinstalled before the new
is (re-)built.

	
>How-To-Repeat:
	
>Fix:
Suggested solution is changing the library path during the build to make
sure that the freshly built libraries get precedence over the installed
libraries.
