That's because lib/wx/src/Makefile makes an unreasonable assumption that host
OS's "sed" command happens to be the GNU implementation. As a workaround,
change this rule:

  $(APP_TARGET): $(APP_SRC) ../vsn.mk Makefile
	sed -e 's;%GEN_MODS%;$(GEN_MODS);' $< > $@.tmp
	sed -e 's;%VSN%;$(VSN);' $@.tmp > $@
	rm $@.tmp

to use GNU sed instead. Alternatively, change GEN_MODS definition to:

  GEN_MODS        = $(GEN_FILES:gen/%.erl=%,)

(Surely you won't mind wx.app will end up looking less pretty than intended).
Alternatively, just hand-edit wx.app changing ",n" to ",<newline>".

HTH,
