Mac Forum / Programming / Perl / August 2006

Hello.

I'm having trouble installing XML::LibXML::XPathContext on a Intel  
Mini (via CPAN). I had no problem installing it on my Powerbook, so  
I'm wondering if it has to do with a difference between PowerPC and  
Intel processors (for lack of any other evidence). Has anyone else  
had trouble installing XML::LibXML::XPathContext?

There are a few warnings about arguments differing in signedness  
during compilation, and a truly amazing number of test failures  
(failing 200% and 183%, if the numbers are to be believed.)

One thing I'm wondering about is the following warning:
/usr/bin/ld: warning -L: directory name (/usr/local/lib) does not exist

I've tried creating /usr/local/lib and installing again, but not  
surprisingly it just removes the warning: I still get the same number  
of test failures. Checking this directory on my Powerbook (with the  
successful XML::LibXML::XPathContext install), I see a number of  
libraries, but none of them look like they have any connection with  
XML (libnmz, libreadline, libsqlite3, libruby, libfcgi, libchasen,  
libhistory, libapreq).

Please find my version and install logs below. I've Googled on some  
of the error strings, but nothing except for a CPAN install failure  
log on an older version of Darwin from 7 months ago[1] have risen to  
the surface.

Thanks for any insight, pointers to documentation, or suggestions of  
things I might try to get it installed are most appreciated.
