error creating postgis25 extension on postgis 11

Hi,

On my Oracle Linux 7 box I had troubles vreating a postgis extension:

create extension postgis

The error is:
SQL Error [XX000]: ERROR: could not load library "/usr/pgsql-11/lib/
postgis-2.5.so": /usr/pgsql-11/lib/postgis-2.5.so: undefined symbol:
geod_polygon_init
ERROR: could not load library "/usr/pgsql-11/lib/postgis-2.5.so":
/usr/pgsql-11/lib/postgis-2.5.so: undefined symbol: geod_polygon_init

This might be a packaging error in the postgis25_11 package for Oracle
Linux 7.
I tried to create a ticket for this issue, however I'm not sure if this
worked out correctly.

I'm sending this mail just to be sure...

[root(at)ol-pg11 lib64]# uname -a
Linux ol-pg11.rihu-ho 4.1.12-124.20.7.el7uek.x86_64 #2 SMP Wed Oct 24
14:15:06 PDT 2018 x86_64 x86_64 x86_64 GNU/Linux

[root(at)ol-pg11 ~]# yum list installed | grep proj
proj.x86_64 4.8.0-4.el7 @epel
proj49.x86_64 4.9.3-3.rhel7.1 @pgdg11

Indeed there are 2 dependencies in my postgis25_11 package:

[root(at)ol-pg11 ~]# yum deplist postgis25_11
Loaded plugins: langpacks, ulninfo
package: postgis25_11.x86_64 2.5.0-1.rhel7.1
...
dependency: libproj.so.0()(64bit)
provider: proj.x86_64 4.8.0-4.el7
dependency: libproj.so.12()(64bit)
provider: proj49.x86_64 4.9.3-3.rhel7.1
...

postgis-2.5.so seems to be using the one in the /lib64 directory:

[root(at)ol-pg11 lib]# ldd postgis-2.5.so
...
libproj.so.0 => /lib64/libproj.so.0 (0x00007f6792485000)
...

The proj4.8 version is located in /lib64

[root(at)ol-pg11 lib]# cd /lib64/
[root(at)ol-pg11 lib64]# ls -l libproj.so*
lrwxrwxrwx. 1 root root 16 Oct 29 13:36 libproj.so.0 -> libproj.so.0.7.0
-rwxr-xr-x. 1 root root 338168 Jan 24 2014 libproj.so.0.7.0

Whereas the proj4.9 version is located in /usr/proj49/lib

[root(at)ol-pg11 lib64]# find / -name libproj.so.12
/usr/proj49/lib/libproj.so.12

The postgis25_11 package should only reference the the proj4.9 version.
Once I fix this manually by changing the symlink I am able to create the
postgis extension.

The permanent option is to fix the package, hope you agree on this,

Kind regards,
Richard.
