o Older freetype2 versions have a different path for ftheader.h, also check for
  it in order to avoid forcing dependency to the pkgsrc version of
  graphics/freetype2. For more information please give a look to pkg/49878.
o test(1) does not support the "==" operator. Use the "=" operator to compare if
  two strings are identical.
