www/opera on FreeBSD

[Frédéric Fauberteau <triaxx%NetBSD.org@localhost>]

I tried to run www/opera on FreeBSD.
$ uname -a
FreeBSD cocoon.triaxx.org 12.1-RELEASE-p3 FreeBSD 12.1-RELEASE-p3 GENERIC  amd64

The package built successfully but libraries seem to be missing. First I tried to build the package with the "native" FreeBSD emulation. 
$ bmake show-var VARNAME=EMUL_TYPE.freebsd
native
$ opera 
ld-elf.so.1: Shared object "libfreetype.so.9" not found, required by "opera"

Then, I tried the builtin emulation.
$ bmake show-var VARNAME=EMUL_TYPE.freebsd
builtin
$ opera
ld-elf.so.1: Shared object "libfreetype.so.9" not found, required by "opera"

Actually, I did not understand what these two emulation types are expected to do. When I look at the resolution of shared objects, I notice that many are missing.
$ ldd /usr/pkg/lib/opera/opera 
/usr/pkg/lib/opera/opera:

        libc.so.7 => /lib/libc.so.7 (0x801d21000)

When I search for freetype library on the system, I only find the one provided by pkgsrc.
$ find / -type f -name "libfreetype*"
/usr/pkg/lib/libfreetype.la
/usr/pkg/lib/libfreetype.a
/usr/pkg/lib/libfreetype.so.6.17.1

If I look at the print/freetype2 provided by FreeBSD ports, that is the same version of the library.

Even with LD_LIBRARY_PATH set to /usr/pkg/lib, libfreetype.so.9 is not resolved.
