[PD] iemmatrix missing externals on win32

[Patrice Colet]

Hello, I'm playing with some iemmatrix objects on win32, pd-extended 0.43.1, and got the following error message in console when trying [mtx_ei~]

I could find almost all objects scattered in pdx, but not [mtx_pcolor], what is this object standing for?
