Ok, I made headway on this... VERY STRANGE ... I found some packages that were
installed to support GEOS showed a certain version with the "pkg info" command
but when I tried to deinstall and make clean inside that version, it said the
package was not installed.  I would then go into another port version... and
THEN I could deinstall even though pkg info showed a different version.  I
don't get it.  Anyhow, I deinstalled all Postgis dependencies, make clean and
then reinstalled them.  NOW, the pkg info command shows the correct version and
all dependencies installed without a problem (including geos).  However, I have
one remaining problem:

"./liblwgeom/.libs/liblwgeom.so: undefined reference to
`geos::operation::valid::IsValidOp::getValidationError()'
../liblwgeom/.libs/liblwgeom.so: undefined reference to
`geos::io::WKBReader::read(std::__1::basic_istream<char,
std::__1::char_traits<char> >&)'

../liblwgeom/.libs/liblwgeom.so: undefined reference to

I cannot explain this.  This is on make install clean for:
 /usr/ports/database/postgis21
