Building Libreoffice 3.6 on OpenIndiana x86 with GCC

After a long time of leaving it, I recently tried to compile
LibreOffice again from updated source.

the ICU that needs to be compiled in 3.6 does not compile on
Solaris/OpenIndiana ... I have managed to get the latest source
(icu4c) from icu-project and fix it so that it compiles on  Solaris
with GCC (I've submitted a patch to them that will hopefully fix it
for everyone).

apart from the fact that it always seems to tell me that it is the
dictionaries that failed to build; I have an error in "(79/83)
Building module tail_build":

Cannot link against library/libraries -lsocket. Libraries must be
registered in Repository.mk.  Stop.

        Oh dear - something failed during the build - sorry !
  For more help with debugging build errors, please see the section in:
            http://wiki.documentfoundation.org/Development

  internal build errors:

ERROR: error 512 occurred while making /home/sal/LibreOffice/libo/tail_build/prj
ERROR: error 512 occurred while making
/home/sal/LibreOffice/libo/dictionaries/source

 it seems you are using a threaded build, which means that the
 actual compile error is probably hidden far above, and could be
 inside any of these other modules:
     tail_build
 please re-run build inside each one to isolate the problem.

build_error.log should contain the captured output of the failed module(s)

-----------------------------------------------------------------------
To rebuild a specific module:

/usr/bin/gmake dictionaries.clean # optional
/usr/bin/gmake dictionaries

when the problem is isolated and fixed, re-run '/usr/bin/gmake'
gmake[1]: *** [build-packimages] Error 1
gmake[1]: Leaving directory `/home/sal/LibreOffice/libo'
gmake: *** [all] Error 2


my question is, how do I tell "Repository.mk" that it should be using
"-lsocket" in tail_build ?

Thanks in advance.
