Comment (by robe):

 fundamental issue seems to be with the pkg-config/proj.pc, if I copy the
 8.2.1 one except changing the paths and version number it gets thru
 compile.  Testing now to see if this fixes the fuzzy issue too.

 the original for 9.8.1 pkgconfig/proj.pc looks like


 {{{
 prefix=/projects/proj/rel-proj-9.8.1w64
 libdir=${prefix}/lib
 includedir=${prefix}/include
 datarootdir=${prefix}/share
 datadir=${datarootdir}/proj

 Name: PROJ
 Description: Coordinate transformation software library
 Requires:
 Version: 9.8.1
 Libs: -L${libdir} -lproj_9
 Libs.private: -lstdc++ -lgcc_s -lgcc_s
 Requires.private: sqlite3 libtiff libcurl
 Cflags: -I${includedir}
 }}}

 I changed it to essentially the 8.2.1 version but replacing the version
 number references

 {{{
 prefix=/projects/proj/rel-proj-9.8.1w64
 exec_prefix=${prefix}
 libdir=${exec_prefix}/lib
 includedir=${prefix}/include
 datarootdir=${prefix}/share
 datadir=${datarootdir}/proj
