PostGIS 3.1 still has a dependency on SFCGAL but it should not - Mailing list pgsql-pkg-yum

Can you check and see why the Yum postgis 3.1.2 still has a dependency on
SFCGAL. I'm not sure if it's a hard-coding you have in place or I missed
something when removing from PostGIS 3.1

In PostGIS 3.1 I removed the dependency on sfcgal from the core library so
that there are two .sos

postgis-3.so
postgis_sfcgal-3.so

But after installing postgis 3.1.2 on CentOS 7 and AMZN-2-Linux I still see
the dependency and it's causing an issue with my ability to do 

CREATE EXTENSION postgis; 

on AMZN-2 -Linux cause I presume the micro version amzn-2 boost-1.5.3.28 is
incompatible (gives error _ZN5boost7archive18text_iarchive_implIN50_13_..)
with 
the epel one you were expecting of boost-1.5.3.30

Anyway that's how discovered that yum.postgresql.org postgis-3 build still
has a dependency on SFCGAL.

That said, I thought maybe I missed something.  I checked my windows build,
and these are separate and all the Boost/SFCGAL  dependency is in
postgis_sfcgal.so.


I checked yum 3.1 install on my CentOS-7 testing box -
yum install postgis31_12 

ldd -d /usr/pgsql-12/lib/postgis-3.so

and I see these lines
        libSFCGAL.so.1 => /lib64/libSFCGAL.so.1 (0x00007f44b96d1000)
        libCGAL.so.11 => /usr/lib64/libCGAL.so.11 (0x00007f44b799d000)

/usr/lib64/libboost_serialization-mt.so.1.53.0 (0x00007f44b69f9000)

and there is no corresponding postgis_sfcgal-3.so I was expecting to see.


On my Ubuntu 20.04 that is using apt.postgresql.org  

ldd  /usr/lib/postgresql/12/lib/ postgis-3.so

shows no boost or SFCGAL dependencies, just has the stuff I'd expect to see
and there is a separate postgis_sfcgal-3.so
