During deployment the modules should be installed somewhere in @INC to be reachable by the perl interpreter. However, installing the modules to a location outside of the PG installation makes it hard to have a consistent environment when running multiple PG versions on the same host. What do you think about defining a canonical place for pl/perlu .pm modules (i.e. PKGLIBDIR) and adding this location to @INC during the interpreter initialization ? Another idea is to allow a user to specify such location by adding a new custom GUC variable.

That has nothing to do with what you asked about, namely setting the
include path. You can set the include path in on_perl_init with "use
lib" and then "use" your modules in your plperlu functions, at which
point SPI will be available.
