following up on the notion that it's compiler/configure related, I did a 
comparison of configure output the buildbot server and my system!

This 1st output is from the buildbot server ...

gcc (Ubuntu/Linaro 4.8.1-10ubuntu9) 4.8.1:

Just a few entries of interest here /not/ all of them ... compare them 
with below output!

Language constructs and functions
---------------------------------
checking size of int... 4
checking size of long int... 8
checking size of size_t... 8
checking size of float... 4

Floating Point Features
-----------------------
checking limits usability... yes
checking limits presence... yes
checking for limits... yes
checking whether NaNs are supported... yes
checking cmath usability... yes
checking cmath presence... yes
checking for cmath... yes
checking whether NaNs can be identified using std::isnan()... no
checking whether NaNs can be identified using global isnan()... no
checking whether NaNs can be identified by comparison to themselves... no
checking whether infinite values are supported... yes
checking for cmath... (cached) yes
checking whether infinities can be identified using std::isinf()... no
checking whether infinities can be identified using global isinf()... no
checking whether infinities can be identified by comparison to the 
maximum value... yes

------

This output is from my system ...

gcc (SUSE Linux) 4.6.2:

Compare to above buildbot output ...

Language constructs and functions
---------------------------------
checking size of int... 4
checking size of long int... 4
checking size of size_t... 4
checking size of float... 4

Did /not/ even have "Floating Point Features" section on my system!!!

The plot thickens? mkl?
