Python 2 or 3 is required for xcb-proto and libevdev.  In the past is was
only python2.  I guess we need to add it to Qt5.  I don't know if it is
required for qt4 or not.

Was I wrong on this? I see no change in either BLFS Errata or Development BLFS. If changes are pending, no problem. However, I wonder if my question is still sound.

But as another example, gobject-introspection-1.44.0 lists only Glib-2.44.1 as a requirement, but also seems to require Python2. I compiled Glib-2.44.1 with only Python-3.4.3, but gobject-introspection-1.44.0 fails during "make" with the following:

Makefile:1871: recipe for target '_giscanner_la-giscannermodule.lo' failed
   make[2]: *** [_giscanner_la-giscannermodule.lo] Error 1
   make[2]: Leaving directory '/sources/gobject-introspection-1.44.0'
   Makefile:2702: recipe for target 'all-recursive' failed
   make[1]: *** [all-recursive] Error 1
   make[1]: Leaving directory '/sources/gobject-introspection-1.44.0'
   Makefile:1480: recipe for target 'all' failed
   make: *** [all] Error 2

The errors don't specify Python2, but after compiling it gobject-introspection compiles successfully. I'm running BLFS 7.8 without problems. My guess is few compile only Python3 so my post remains merely a question as it shows only my experience. Perhaps I've done something else wrong, but BLFS 7.8 is performing well and compiling Python-2.7.10 is an easy fix..
