  You have to fix the linker to use that library instead of the system one.

  Edit src/modules/rlm_perl/all.mk, and set TGT_LDLIBS to that path:

TGT_LDLIBS :=  <foopath>/perl/lib/5.26.3/x86_64-linux-thread-multi/CORE/ libperl.so

  And rebuild.

  It's generally a bad idea to install two versions of the same library on a system.  It's not well supported by the linker, and it has a tendency of breaking.

  i.e. you can tell FreeRADIUS to use one library, but the system might just choose another one.  There isn't a lot you can do to work around that, other than fix the system.
