I suppose you must also pass the -custom flag to the compiler, because the
C functions lex_engine_tiny_8bit and lex_engine_tiny_utf8 are not available in
the standard bytecode interpreter. (But "Error while building custom runtime
system" is a hint that ocamlc tries to build a custom runtime system; this
message is confusing.)

I remember also that there are two versions of wlex, one using a lexing engine
written in C, and another one using a lexing engine written in O'Caml. XPath
seems to use the C version (applies module Lex_engines, not Lex_engines_ml
in xpath_wlexer.mll).

If that does not help, I need the output of
 
camlfind ocamlc -verbose -o test -linkpkg -I .. xpath.cma -package pxp,wlexing
   test.cmo

(added the -verbose option), plus the exact version numbers of the packages
pxp, wlexing, and xpath to track the error.
