I took a look at glabels, and I am assuming others ports have similar
problem.
The error log is:
/usr/bin/libtool --tag=CC --mode=link cc ...
warning: could not find a edbus-private library
Link error: edbus-private not found!

it is libtool that generate an error because it didn't found
edbus-private library.
This particular library comes from databases/evolution-data-server :
$ pkg_locate edbus-private
evolution-data-server-3.28.5:databases/evolution-data-server:/usr/local/lib/evolution-data-server/libedbus-private.so
So with ld.lld, libtool is unable to found the library.
I am able to reproduce the problem with just the following command line:
$ libtool --tag=CC --mode=link cc -v -o test -lebook-1.2
warning: could not find a edbus-private library
Link error: edbus-private not found!
...
For what I understood, libtool uses objdump -p libebook-1.2.so to found
the path dependencies (I have ktraced libtool).
On pre-ld.lld system, I have the following output:
$ objdump -p /usr/local/lib/libebook-1.2.so.21.0
...
Dynamic Section:
NEEDED libedata-book-1.2.so.18.0
...
NEEDED libedbus-private.so
...
RPATH /usr/local/lib/evolution-data-server
...
But on post-ld.lld, the output is slightly different:
$ objdump -p /usr/local/lib/libebook-1.2.so.21.0
...
Dynamic Section:
RUNPATH /usr/local/lib/evolution-data-server
NEEDED libedata-book-1.2.so
...
NEEDED libedbus-private.so
...
So ld.lld uses RUNPATH instead of RPATH, and as libtool only uses RPATH
to infer no standard directories... it fail to found the library.
The following diff on libtool permits to productivity/glabels to build.
