NOTE:
As seen above, the boost-lib and boost-jam are required for libreoffice
compilation.
I see missing '+REQUIRED_ BY' file in their package dirs:
 /var/db/pkg/boost-libs-1.48.0/
+COMMENT        +CONTENTS       +DESC           +DISPLAY        +MTREE_DIRS
# ls /var/db/pkg/boost-jam-1.48.0/
+COMMENT        +CONTENTS       +DESC           +MTREE_DIRS

So, what was the trick with boost removal ?
If none, then what was the fix (this should be stated before closing the PR).
