trouble building subversion 1.4.0 on QNX Neutrino v6.3.0

I was looking forward to building a subversion client on my
QNX box, but I can't get configure to run successfully.
Could you please help?

I am attempting to build subversion 1.4.0 on QNX Neutrino 6.3.0.
I have downloaded and unpacked subversion-deps-1.4.-.tar.gz.

At first, configure told me that I needed XML2, which I installed using
the
QNX installer utility. Now configure gives me this error:

checking whether to enable ACL support in neon... yes
configure: SSL support is not enabled
configure: SOCKSv5 support is not enabled
checking for krb5-config... none
configure: WebDAV support is enabled
checking expat.h usability... no
checking expat.h presence... no
checking for expat.h... no
checking for xml2-config... xml2-config
checking libxml/xmlversion.h usability... yes
checking libxml/xmlversion.h presence... yes
checking for libxml/xmlversion.h... yes
checking libxml/parser.h usability... no
checking libxml/parser.h presence... no
checking for libxml/parser.h... no
configure failed for neon

It is puzzling that it is able to find libxml/xmlversion.h but is not
able
to find libxml/parser.h. They are in the same directory:

find / -name parser.h
/opt/include/libxml2/libxml/parser.h
/usr/include/libxml2/libxml/parser.h
/usr/include/libxml/parser.h

find / -name xmlversion.h
/opt/include/libxml2/libxml/xmlversion.h
/usr/include/libxml2/libxml/xmlversion.h
/usr/include/libxml/xmlversion.h

The copies of parser.h and xmlversion.h in /usr/include are symbolic
links
back to the copy in /opt/include. This was done by the QNX installer
utility.

xml2-config gives the following outputs:

$ xml2-config --libs
-L/opt//lib -lxml2 -lz -liconv -lm -lsocket

$ xml2-config --cflags
-I/opt//include/libxml2

$ xml2-config --version
2.4.21

I have attached config.log. Hopefully it contains some clues.

I have tried invoking configure with the arguments:

CFLAGS=-I/opt/include/libxml2/
CPPFLAGS=-I/opt/include/libxml2/
CXXFLAGS=-I/opt/include/libxml2/

in an attempt to explicitly tell configure where to find parser.h.
It did not work.

If this looks like it can't be solved, is there a way that subversion
can be
compiled without neon (which seems to be the root of all this trouble)?

Thank you very much for your help.
