First, I bootstrapped pkgsrc into $HOME/bulk:
<pre><code>
$ cd
$ env \
     CC=cc \
     CXX=CC \
     MIPSPROBASE=$HOME/mipspro-wrapper \
     ./proj/pkgsrc/bootstrap/bootstrap \
         --prefix=$HOME/bulk \
         --unprivileged \
         --compiler=mipspro \
         --quiet
...
</code></pre>
Then, make a backup copy of LOCALBASE:

     $ tar cfz bulk.tar.gz bulk

It is a good idea to store all configuration files outside of *LOCALBASE*:

     $ mkdir bulk-etc
     $ cp bulk/etc/mk.conf bulk-etc/.

Like on Solaris, I needed to comment out the *pre-build* script. The configuration files look similar to the ones from the Solaris build.

To get a usable environment, I have built some package before in $HOME/pkg, so that I can link to them (for example *ginstall* and *groff*).
<pre><code>
$ screen -S bulk
$ sh proj/pkgsrc/mk/bulk/build -c /usr/people/rillig/bulk-etc/build.conf

bmake: exec(/bin/sh) failed (Arg list too long)
*** Error code 1

Grmpf. IRIX has only 20k for the command line and the environment, and that gets filled pretty quickly. Let's see what's the cause for that. It's the command starting with "${RUN} set +e;" and going until the lonely "fi" in line 534. That's pretty much. Since I don't know how to break that into smaller chunks, I stop here.
#Some hours later

I've made some progress. I didn't rewrite the bulk builds but simply patched bmake to create a temporary file and write the overly long command lines there when an execve fails due to E2BIG. I applied [this patch](ftp://ftp.netbsd.org/pub/pkgsrc/misc/rillig/bmake-irix.patch) in the devel/bmake directory and re-ran bootstrap. Things seem to work now.

At least, [lang/perl](http://pkgsrc.se/lang/perl) is building, which takes some time. Not to speak of the database generation that follows. Meanwhile, I'm adding the following to the [[pkgsrc/mk.conf]] file, just as in the Solaris bulk build:
<pre><code>
BULK_PREREQ+=		pkgtools/bootstrap-mk-files
BULK_PREREQ+=		pkgtools/tnftp
BULK_PREREQ+=		pkgtools/mtree
BULK_PREREQ+=		pkgtools/pax
BULK_PREREQ+=		pkgtools/pkg_install
BULK_PREREQ+=		sysutils/mtree

BULK_PREREQ+=		sysutils/checkperms
