 Hauke,
 
 It appears this MIGHT actually be a gcc issue??  In my environment,
 the compiler flag -fvisibility=hidden is passed (see below,) but that
 is not supported by older gcc versions (sorry not sure which version
 got it added... looks like maybe added in 4.0, but I see you are using
 4.1.2?)  Anyhow, below is the error seen when building with gcc-3.4.6
 on Solaris:

 I got the library to compile and install cleanly by adding:
   BUILDLINK_TRANSFORM+=   rm:-fvisibility=hidden
 to the Makefile.  I am unclear what affect this has on the resulting
 library... apparently some internal functions will be visible that
 should be hidden, but unless those cause a name collision, I think it
 would not affect use of the libraries.  It does seem that this was
 added very recently to boost, as prior version did not show this error
 in the same build environment.
 
 Perhaps wrapping the above in .if !empty(CC_VERSION:Mgcc-[23]) .endif
 would be ok?
 
 The existing info in the PR does not include the lines above
 "...failed gcc.compile.c++.pch
 
bin.v2/libs/math/build/gcc-3.4.6/release/link-static/threading-multi/../src/tr1/pch.hpp.gch..."
 which would indicate the actual failure and if it was the same as the
 one I see or something else?
 
 Could you try building with the BUILDLINK_TRANSFORM line added to your
 Makefile, and/or provide the errors encountered above the ...failed
 line?
 
 Thanks,
