modules(i.e. PKGLIBDIR) and adding this location to @INC during the interpreter initialization ? Another idea is to
allowa 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.
