[Libreoffice] build error with stlport

I'trying to build --with-stlport on i686 for ArchLinux. The build fails
here in "sw" using system boost 1.46.0:

collect2: ld returned 1 exit status
dmake:  Error code 1, while making '../unxlngi6.pro/lib/libswli.so'

and when adding --without-system-boost:

Compiling: rsc_sw

Making:    libswli.so
/usr/bin/ld: cannot find -lboost_thread-mt
collect2: ld returned 1 exit status
dmake:  Error code 1, while making '../unxlngi6.pro/lib/libswli.so'


I only found some notes about ixion and fields-table-formula.diff
probably breaking this.

Any idea about this?
