lua-luahpdf fails to install on Mavericks wich macports 2.2.1

[roberto.avanzi@…]

When I try to install lua-luahpdf I obtain following error

ravanzi-mac:build mocenigo$ sudo port install lua-luahpdf
--->  Computing dependencies for lua-luahpdf
--->  Building lua-luahpdf
Error: org.macports.build for port lua-luahpdf returned: command execution failed
Please see the log file for port lua-luahpdf for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_lua-luahpdf/lua-luahpdf/main.log
To report a bug, follow the instructions in the guide:
    http://guide.macports.org/#project.tickets
Error: Processing of port lua-luahpdf failed

I am not sure why. May be a CLANG/GCC thing and this leaves something undefined, however I get the following error in the log

hpdf.c:265:17: error: use of undeclared identifier 'LUA_ENVIRONINDEX'
also
hpdf.c:3732:16: error: unknown type name 'luaL_reg'; did you mean 'luaL_Reg'?

and then other commands fail.
