 webkit-gtk has a strange build problem for me on Snow Leopard. I get this
 error:

 {{{
   CXX    JavaScriptCore/pcre/libJavaScriptCore_la-pcre_tables.lo
 In file included from JavaScriptCore/pcre/pcre_tables.cpp:73:
 JavaScriptCore/pcre/chartables.c:13: error: conflicting declaration 'const
 unsigned char jsc_pcre_default_tables [0u]'

 make[1]: *** [JavaScriptCore/pcre/libJavaScriptCore_la-pcre_tables.lo]
 Error 1
 make: *** [all] Error 2
 }}}

 Line 382 of pcre_internal.h reads:

 {{{
 extern const unsigned char jsc_pcre_default_tables[tables_length];
 }}}

 And earlier in that file we have:

 {{{
 #define cbit_length   96      /* Length of the cbits table */
 }}}
 {{{
 #define cbits_offset  256
 #define ctypes_offset (cbits_offset + cbit_length)
 #define tables_length (ctypes_offset + 128)
 }}}

 So that looks fine. But in chartables.c on line 13 we have:

 {{{
 const unsigned char jsc_pcre_default_tables[0] = {
 }}}

 That's wrong. And in fact, chartables.c ends with the line:

 {{{
 /* This table is a case flipping table. */
 }}}

 (There should be a lot more after that line.)

 If I manually run dftables (the program that creates chartables.c), a
 complete correct-looking file is created.

 If I delete chartables.c and rerun the port install, it recreates
 chartables.c correctly.

 I think it's a parallel build issue. dftables tries to read values from
 pcre_internal.h, and this will fail if pcre_internal.h has not been
 written yet.
