As we discussed on IRC, I tried [1] on Ubuntu. It worked like what on my Mac.
I read a little bit Pango source code. It seems to me that there is no way to create PangoFont or PangoFcFont from FT_Face without adding new API to Pango.
And the reason why my code works is that Pango can use FreeType without using FontConfig. The PangoFcFont is kinda misnomer, I think. PangoFcFont is can be Xft font, FreeType Font, or FontConfig+FreeType font
