Windows 98 Installation Problem

Hi, I'm trying install PEAR in my Windows 98, I have lynx for win32, and I have PHP-GTK 0.5.1 for win32, ie I have PHP 4.3.0dev, which works just fine, but when I trying run the command: lynx -source http://pear.php.net/go-pear | php -q It work correct until try extract Installer and report an error message like: could not acquire shared lock (c:\php4\pear\.lock) and the installation ends up before completion. This is the install log Welcome to go-pear! Go-pear will install the 'pear' command and all the files needed by it. This command is your tool for PEAR installation and maintenance. Go-pear also lets you download and install the PEAR packages bundled with PHP: DB, Mail, XML_Parser. If you wish to abort, press Control-C now, or press Enter to continue: HTTP proxy (host:port), or Enter for none: Below is a suggested file layout for your new PEAR installation. To change individual locations, type the number in front of the directory. Type 'all' to change all of them or simply press Enter to accept these locations. 1. Installation prefix : c:\php4 2. Binaries directory : $prefix 3. PHP code directory : $prefix\pear 4. Documentation base directory : $php_dir\docs 5. Data base directory : $php_dir\data 6. Tests base directory : $php_dir\tests 1-6, 'all' or Enter to continue: The following PEAR packages are bundled with PHP: DB, Mail, XML_Parser. Would you like to install these as well?
