A FreeBSD port of penv is available at http://devel.ringlet.net/sysutils/penv/penv-1.2p1.shar, as well as in the FreeBSD Ports Collection as sysutils/penv.
To install penv from its source distribution, follow this procedure:
Acquire the source distribution
The penv source distribution may be obtained from its home page, http://devel.ringlet.net/sysutils/penv/. The current version of penv is 1.2p1; a source tarball may be obtained directly from http://devel.ringlet.net/sysutils/penv/penv-1.2p1.tar.gz.
Another way to acquire the penv source distribution would be to access Ringlet's CVS repository and check out the penv module. However, for the present, the Ringlet CVS repository is not available online for anonymous access.
Unpack the penv source
If you have fetched the penv tar/gzip source archive, you will need to unpack it using the command:
% tar -zxf /path/to/penv-1.2p1.tar.gz
Configure the penv build settings
This and the following steps should be performed from within the penv source directory. If you have obtained the penv sources via CVS, this directory would be named simply penv/. If you have obtained a tar/gzip source archive, the directory will be named penv-1.2p1/.
Edit the appropriate Makefile for your system. If you are on a GNU/Linux system, or you are using GNU make on some other system, you need to edit the GNUmakefile. If you are using a BSD version of make or the pmake portable version, you need to edit the Makefile.
There are two build-time configuration options that you may enable by uncommenting the lines that add them to the CFLAGS_COMPAT make variable:
Once the configuration step is complete, it is time for the actual penv build. All you need to do is issue the following command:
We are almost there! :) penv has been successfully built, now all you need is to install it. Just like with many other programs, this is done with the following command:
# make install
Note: You may need to obtain root privileges to install penv in a location outside your home directory or the system /tmp directory.
And that is all there is to it! :)
