How about the following method?
* configure script checks whether Pango's version is 1.38 or above.
* If Pango's version is 1.38+, configure makes that `config.hh` defines
something like `HAVE_PANGO_1_38`.
* In `lily/pango-font.cc`, enclose around `pango_attr_font_features_new ()`
with `#ifdef HAVE_PANGO_1_38` and `#endif`.
* In the else clause it may be better to show a warning message that this
binary cannnot use OpenType font features.
In this method, the binary that is builded by GUB can use OpenType font
features since GUB has Pango 1.40.1.
So you can use OpenType font features in the binary distributed by lilypond.org.
LilyDev 4.1 also can compile it.
However, the binary cannot use OpenType font features.
If you compile .ly file that uses OpenType font features by the binary, you
would see the warning message that this binary cannot use OpenType font
features.

** [issues:#1388] Support OpenType font features**

Currently, LilyPond doesn't support OpenType font features. For example, many
fonts already contain glyphs for small caps letters, but lilypond can't access
such glyphs directly since OpenType fonts don't need to have named glyphs, and
you need to activate an OpenType feature \(\`smcp' in this particular case\) so
that input character codes get properly mapped to caps glyphs.
I suggest that we implement an interface similar to the \`fontspec' package for
XeTeX and luatex:
