BUG: go-pear install on Win32 installs to wrong drive

It appears that the go-pear installer has a variable gone wrong or something. My OS is installed in D:\WINNT but PHP is installed at C:\PHP4. When I run go-pear it appears to download and install all options correctly (everything reports "ok" and I get the success message at the end) however, c:\php4\pear contains only the following: C:\php4\pear\.filemap C:\php4\pear\.lock C:\php4\pear\.registry C:\php4\pear\data (empty) C:\php4\pear\docs (empty) C:\php4\pear\tests (empty) C:\php4\pear\.registry\Archive_Tar.reg C:\php4\pear\.registry\Console_Getopt.reg C:\php4\pear\.registry\DB.reg C:\php4\pear\.registry\Mail.reg C:\php4\pear\.registry\Net_SMTP.reg C:\php4\pear\.registry\Net_Socket.reg C:\php4\pear\.registry\PEAR.reg C:\php4\pear\.registry\XML_Parser.reg C:\php4\pear\.registry\XML_RPC.reg Everything else is installed to D:\php4\pear\ Sorry for being so awkward! :) Matt
