Subject Re: Problem with RequestRec and Headers
Date Mon, 24 Sep 2007 04:07:50 GMT
I looked at the source.  It does seem to be written for both.  My
understanding was that everything for apache2 was supposed to be in the
Apach2:: namespace.  In any case I posted the install error below.  Does an
environment variable need to be set?


perl Makefile.PL
Warning: prerequisite mod_perl 0 not found.
Writing Makefile for Apache::Singleton

If I install it anyway I get "[Sun Sep 23 15:09:49 2007] [error] Can't
locate Apache/RequestUtil.pm in @INC (@INC contains:......"

Thanks. --JAK
