I guess you did not install wlex or ulex.

The biggest part of the executable are the UTF-8 lexing tables of the
ocamllex-based lexer (about 1M). By switching to the wlex or ulex lexer
(the latter is only present in the newest release, but simpler to
build), you can reduce the size of the executable significantly. These
alternative lexers are a bit slower, however. After building them,
compile your program with -package pxp-engine,pxp-ulex-utf8 or

In general you need only the lexer that corresponds to the internal
representation of the XML data.
