Building LO 4.0.4.2 on illumos based OS

Hi,
I'm working on our Sonicle XStreamOS distro based on illumos kernel.
I encountered some problems building LO 4.0.4.2.
First, I decided to use system libs as much as possible, so I'm building with this configure 
options:
--enable-gtk3 --disable-python --with-system-libs --with-system-altlinuxhyph=no 
--with-system-lpsolve=no --without-java --with-x
I had to disable python because of some problem during build, at the moment.
I will see if I can provide a system python 3.3 later.
After building and packaging all the required system libs, I decided to keep altlinuxhyph and 
lpsolve as internal ones. All the other ones go fine from system.
Then I found that LO needs gnu ld, used ld options don't work with sun ld, so I could use the sun 
ld env
LD_ALTEXEC to force it to run gnu ld once invoked, and build went on almost fine.
I stumbled on on error about "madvise" missing, but I could find a working patch:

if (madvise(static_cast
(p), nLength, MADV_WILLNEED) != 0)
{
OSL_TRACE("madvise(..., MADV_WILLNEED) failed with %d", errno);
basically it disables the call to madvise on my env, then build went on very long over the 
tail_build.
Here, I finally got this strange error:

I can't see why libreg.so can't resolve libstore.so, as they both live in solver/unxsogi.pro/lib :
