OpenVG support does not compile with ShivaVG

I installed ShivaVG 0.2.1 and configured Qt with -openvg. The configure reported

OpenVG support ......... ShivaVG

Compilation of Qt failed with these errors:

It seems that the type QVGFontCache is only conditionally defined if the expression"#if !defined(QVG_NO_DRAW_GLYPHS)" is true. Everywhere in the code where QVGFontCache is used,
there is code conditional on QVG_NO_DRAW_GLYPHS except for the code where the errors occur. The code needs to handle the case where QVG_NO_DRAW_GLYPHS is defined.

Qt 4.6.2 successfully built with ShivaVG support.
