The python involvement was another thing I thought about, but didn't go 
there as I had nothing really concrete to go on, other than just a tingle of 
a hunch/question/doubt. On a 9.3 box here I have:


whilst on the 10.0 box I show:


I'm left wondering if the top line on the 9.3 machine may be cruft.

pkg info -r <packagename>  shows reverse dependencies and
pkg info -d <packagename> will show dependencies of installed package

I'm uncertain as to how python gets involved in a build process. Something I 
look at from time to time wrt to build questions are to rummage around and 
grep stuff in /usr/ports/Mk in order to attempt to gain understanding on what 
default build path(s) and/or options might exist.

Such things change from time to time and require associatted alterations in 
/etc/make.conf - example such as WITH_BDB_VER=5, DEFAULT_VERSIONS+=php=5.3 
mysql=5.6 apache=2.2, etc, and such. Another is WITH_PKGNG= yes I have in 
make.conf on the 9. box as I believe it's supposed to be there and yet it is 
not present on the 10.x box as I believe it's not required in 10.x. 

Certainly not much here on my end to go on - just brainstorming. Hope you 
get it sorted.
