I really _hate_ to insist - I asked about reasons, because I got POV
3.7 compiled with Boost 1.36, and it seems to work normally. 

Shouldn't there be execution problems, or has this only effect on the
image quality/contents?

This is a complex boost change, not a change in POV-Ray. Please read the 
*boost* documentation, as this is not a POV-Ray issue! Do no use boost 1.35 
or later with the current POV-Ray 3.7 beta source code if you want a 
functional executable. The fact that a program compiles and links does not 
make it function correctly. There is nothing wrong with either boost 1.36 or 
POV-Ray 3.7, you just have to use the correct version of boost. Use boost 
1.34 with the current POV-Ray 3.7 beta source code.

Hello,
I am using 1.39 version now, and I met the same issue on using libboost_thread
even I use ln -s command. any guys can help me how to do that?
My email address is wis### [at] intelcom
I am using below command:
.../configure --prefix=/home/spd/wchen18/povray/povray-3.7.0.beta.32
--with-boost=/net/spd64/home/spd/wchen18/povray/libs/boost_1_39_0/stage/lib
--with-boost-thread=libboost_thread-gcc43-mt  COMPILED_BY="Wise Chen"

check your version number looking in <boost/version.hpp>. See
