Re: Pkgsrc on linux, defective by design ?
Out of total curiosity (and I know I shouldn't be asking this but
anyhow) WHY are you trying to use PKGSRC on CentOS?
There is little sense to be made of that.
CentOS by choice ships older (known stable and secure) code and PKGSRC
by comparisson (in many cases not all) ships newer releases. There are
conflicting ideals at work here and you will have issues as a result.
You will find that PKGSRC works much more happily on something like
Fedora 13 for example.
Although I find a Slackware derivative like a very minimal Slax
the most comfortable with PKGSRC
And to add to it.... almost anything you could possibly need you will
find in a binary form compiled for CentOS/RHEL/OracleEL in a repo.
thats what the package manager is there for and in any case you can
quite easily build RPMs against CentOS and host you're own repo quite
What is it that you are trying to accomplish?
