php 5.2.3 configure/install problem

["Alan Kong" <aklx@xxxxxxxxxxxxxx>]

Hi,
I configured php5.2.3 on Sparc Soalris 2.9 using gcc 3.4.6 and encountered 
the following problem:
# ./configure --prefix=/usr/local/php.5.23 --with-apxs=/usr/apache2/bin/apxs 
\
> --with-gettext --with-dom \
> --with-iconv --enable-mbstring=all --enable-mbregex \
> --with-mysql=/usr/local/mysql
creating cache ./config.cache
checking for Cygwin environment... no
checking for mingw32 environment... no
checking for egrep... egrep
checking for a sed that does not truncate output... /usr/local/bin/sed
expr: syntax error
../configure: test: argument expected

The php compiled will be used for the horde package on building webmail.

I obtained similar problem when configured with php4.4.7

Please help/advise on solving the problem.

Thank you.

Regards
Alan
