mkl is Math Kernel Library (Intel) It's a math speed up library ... and 
from what I've read it's somewhat problematic on unbuntu, however I did 
find a couple of recipes that claim success. I think it's specialized 
enough that if the user wants to run that it's on them ... I think what 
the build process seems to be looking for ends up getting satisfied by 
the libm test that follows the mkl test in configure.ac

from my configure output:
checking for sin in -lmkl... no
checking for sin in -lm... yes

btw: mkl recipes had to build from sources ... there appears to be /no/ 
package available via apt-get so I'm not inclined to pursue

about LIBS switches ... I /had/ LIBS="-lboost_system -lboost_thread" as 
configure additions, but noticed -lboost_system listed /twice/  at the 
end of make ... lasest revisions of povray master and hotfix built ok 
fine using just LIBS="-lboost_thread"
