Update for Quartz-based trunk builds:
After upgrading poppler from 0.18.4 to 0.20.2 (poppler 0.20 migrated from lcms to lcms2), color management seems to be working again in latest Inkscape trunk builds (although the binary still links to both versions of lcms, and lcms2 support is not enabled for osx builds in configure).
Note: These findings need yet to be verified/reproduced with the X11-based build environment (poppler not yet upgraded there), since the Quartz-based build environment also uses newer (unstable) versions of glib2 and glibmm.
