Why won't my custom Perl install into expected directory?

I followed the instructions in this tutorial to build a custom version of Perl.

I originally did step 8 as follows: 

./Configure -d -Dprefix=/custom/perl

After I did that, I did make, make test, and make install.

Then I decided that I want Perl in /opt/perl instead, so I did make clean and repeated the process and did step 8 with the appropriate directory. Still installed into /custom. Then I deleted custom completely and re-installed with the appropriate directory in the ./Configure step. Still installed into /custom.

What am I missing? I want Perl in /opt not /custom.

The -d option to ./Configure causes the build process to source your existing config.sh file. The -Dprefix=... option will override the prefix setting in your existing config.sh, but unfortunately it won't override a number of other options that could be set in config.sh based on an earlier setting for prefix.

In addition to make clean, you also need to rm config.sh in order to safely reuse a perl build directory.

If you intend to copy the settings from your build process to another machine, you'll also want to clean out Policy.sh.

You have the right usage for 5.16, as per its INSTALL file: "You can also specify any prefix location by adding "-Dprefix='/some/dir'" to Configure's args."

So I suspect that make clean does not remove the files created by Configure. Try it from a fresh directory instead of a "cleaned" directory. Or at least try deleting config.sh and Policy.sh.

[Upd: It was pointed out that make distclean can be used to do this. Of course, so can git clean -dfx if you're installing from the repo instead of from the tarball. ]
