It looks as though "the system" doesn't know where to find the=20
ARS API libraries

In the following insructions $ARSAPI refers to the location you set=20
for $ARSAPI in Makefile.PL

Are the $ARSAPI/lib/* libraries registered with the system?
If they are you can find out where it thinks they are by running (as
root)
/sbin/ldconfig -p | grep libars.so

If you get no results back you need to add $ARSAPI/lib to the list of=20
directories that contain libraries. In /etc/ld.so.conf.d/ create a file=20
called ars-api-5.12.conf and add one line to it: $ARSAPI/lib

I'm not sure but you may need to run ldconfig (man ldconfig for the
correct options)=20
to have it register the libraries
