luarocks not finding pcre for lrexlib-pcre on OS X

Hello,

I'm trying to install lrexlib-pcre via luarocks on Mac OS X where I have 
installed pcre via MacPorts. MacPorts puts its files in /opt/local so 
luarocks doesn't find pcre.h. That should be solved by setting PCRE_DIR 
to /opt/local/include/ but it doesn't.

bash-3.2# file /opt/local/include/pcre.h
/opt/local/include/pcre.h: ASCII c program text
bash-3.2# export PCRE_DIR=/opt/local/include/
bash-3.2# luarocks install lrexlib-pcre
Installing 
http://luarocks.luaforge.net/rocks/lrexlib-pcre-2.3.0-1.src.rock...

   inflating: lrexlib-pcre-2.3.0-1.rockspec
  extracting: lrexlib-2.3.0.zip

Error: Could not find expected file pcre.h for PCRE -- you may have to 
install PCRE in your system and/or set the PCRE_DIR variable

Thanks,

Agreed. Just in case it might be helpful to a newcomer, let me mention
http://www.wra1th.plus.com/lua/book/contents.html . Although it was
written for a particular dialect of Lua on a particular platform, some
newcomers, especially those who have met BBC Basic, may find one or two
points useful.

You can also buy yourself a LEGO MINDSTORMS NXT and load pbLua
on it for a fun way to explore Lua with LEGO robotics!

<http://www.hempeldesigngroup.com/lego/pblua>

There's an active LEGO MINDSTORMS community in Amsterdam and
a bit of googling will help you locate them...

A rather belated comment... There was a project by a Japanese 
developer that implemented the VM portion in Lua... not sure if 
it's listed in the wiki, but it popped up on the list before.

Anyway, regarding Yueliang (ref [1]), it's being hacked on a very 
casual basis, and a back-end (VM) is unlikely for now because I 
haven't found an application that is useful enough to apply it to. 
Effort on Yueliang's front end portions were prompted by 
LuaSrcDiet. The possibility of Lua on Lua or Lua on JavaScript 
haven't been as appealing because I have no immediate use for 
those things for now. I am currently just aiming for a native code 
generator with copious documentation. Just FYI in case anyone is 
waiting for progress or anything like that.

I just used this Unidecode module in a small project, and it has been
very useful. However since it has many files and I didn't find how to
download them at once from Trac, I used the nanoki tarball to get it.
Is the module available somewhere separately ? And if not would you
consider releasing it in its own tarball ?
