Problems with new Centos installation (librprUsd.so)

[LucaPrassoDaydreamLabs]

I'm running Houdini 18.5.408 on a Centos VM.
I downloaded the latest RPR 2.0.13 and copied it on a local folder.
I created the proper package JSON file

{
	"env":[
		{
			"HOUDINI_PATH":"$RPR/houdini"
		},
		{
			"PYTHONPATH":"$RPR/lib"
		},
		{
			"RPR":"/netapp/AMDRadeonProRender/hdRpr-2.0.13-Houdini-18.5.408-py3.7-centos7"
		}
	]
}

The installation folder seems OK

ls /netapp/AMDRadeonProRender/hdRpr-2.0.13-Houdini-18.5.408-py3.7-centos7
activateHoudiniPlugin  houdini  include  INSTALL.md  lib  libraries  LICENSE.md  materials  plugin  README.md  version

ls /netapp/AMDRadeonProRender/hdRpr-2.0.13-Houdini-18.5.408-py3.7-centos7/lib
Hybrid.so     libMIOpen.so.2      libNorthstar64.so         libRadeonImageFilters.so.1      libRadeonML_MIOpen.so    libRadeonML_MIOpen.so.0.9.7  libRprLoadStore64.so  libTahoe64.so
libMIOpen.so  libMIOpen.so.2.0.1  libRadeonImageFilters.so  libRadeonImageFilters.so.1.5.4  libRadeonML_MIOpen.so.0  libRadeonProRender64.so      librprUsd.so          python

but when I start Houdini I get

Houdini DSO error on '/netapp/AMDRadeonProRender/hdRpr-2.0.13-Houdini-18.5.408-py3.7-centos7/houdini/dso/RPR_for_Houdini.so'
	librprUsd.so: cannot open shared object file: No such file or directory

What am I doing wrong?

Thanks,
Luca

Never mind... I'm a moron... I had a typo in the JSON file...
