5.2.0 fails; sybase off; connected with pear

["Jay G. Scott" <gl@xxxxxxxxxxxxxxxx>]

i can't compile/install php-5.2.0.

dismayed# uname -a
SunOS dismayed.arlut.utexas.edu 5.10 Generic_118833-17 sun4u sparc SUNW,UltraAX-i2

dismayed# gcc -v

libxml2 compiled with this compiler on this machine.
libxml2-2.6.26
php-5.2.0


below, it's saying it can't find
xmlParserInputBufferCreateFilenameDefault

i checked on that, and turned off sybase.  it's still doing it.

./configure --prefix=$ODEPOT/$GPACK     \
        --with-apxs=/opt/bin/apxs       \
        --with-libxml-dir=/opt/depot/libxml2-2.6.26     \
        --without-sybase --without-sybase-ct

configure output sent to file "progress".

dismayed# grep -i sybase progress
checking for Sybase support... no
checking for Sybase-CT support... no

here's the whole output.

according to what i see (newbie) it's a problem with pear.
what is pear?  i assume i want it.  i'm installing php, i'm not
the end user.  (FWIW)
