error with make on pgadmin3-1.6.2

I am trying to install pgadmin3-1.6.2 on a Redhat enterprise 4 update 4
which is kernel 2.6.9-42

I installed libxml2 2.6.18 without problems
I installed and configured wxWidgets-2.8.0.tar.gz as per the
instructions on http://www.pgadmin.org/download/source.php without any
problems.

I did the ./configure without any problems but when I did make, I get
some errors ( you can see the error in the attached txt file.

./base/pgConnBase.cpp:551: error: `PG_DIAG_INTERNAL_POSITION' undeclared
(first use this function)

./base/pgConnBase.cpp:551: error: (Each undeclared identifier is
reported only once for each function it appears in.)

./base/pgConnBase.cpp:552: error: `PG_DIAG_INTERNAL_QUERY' undeclared
(first use this function)

./base/pgConnBase.cpp:595:2: warning: no newline at end of file

make[2]: *** [pgConnBase.o] Error 1

make[1]: *** [all-recursive] Error 1

make[1]: Leaving directory `/local_appl/pgadmin3-1.6.2'

make: *** [all] Error 2

any help would be appreciated.
