Comment:

 I am able to reproduce the xalanc build failure but I now think this is a
 bug in xercesc3 @3.3.0 because other ports fail with the same message. nco
 for example fails to configure; its config.log says:

 {{{

 }}}

 enigma builds and installs but it fails to run:

 {{{
 % enigma
 dyld[17071]: symbol not found in flat namespace
 (_xercesc_messages_3_2_dat)
 zsh: abort      enigma
 }}}

 I believe the problem is in the file
 src/xercesc/util/MsgLoaders/ICU/ICUMsgLoader.cpp which says:

 {{{#!c
 /*
  *  Resource Data Reference.
  *
  *  The data is packaged as a dll (or .so or whatever, depending on the
 platform) that exports a data symbol.
  *  The application (this *.cpp) references that symbol here, and will
 pass the data address to ICU, which
  *  will then  be able to fetch resources from the data.
  */
 #define ENTRY_POINT xercesc_messages_3_2_dat
 #define BUNDLE_NAME "xercesc_messages_3_2"
 }}}

 Surely for version 3.3.0 that should be `3_3` not `3_2`.
