Reasonable point. It's an Amazon Linux image which is by all accounts really
Centos (poking around on the box confirms).

I'm using bash.

Nor can I. I actually did a 'find / -name "mkmain.sh"' as well as searched the
centos pkg repos for the file and nothing comes up. My colleague suggested that
perhaps mkmain.sh is actually generated by the make process and cleaned up after
the error, leaving me no chance to see it. I grepped around in the ruby build
dirs for mkmain.sh and only see these references:

    $ find . -type f | xargs grep 'mkmain'./Makefile:MKMAIN_CMD    = mkmain.sh
    ./Makefile.in:MKMAIN_CMD    = mkmain.sh
    ./win32/Makefile.sub:MKMAIN_CMD    = mkmain.bat

and then searching for the MKMAIN_CMD string:

    $ find . -type f | xargs grep 'MKMAIN_CMD'
    ./Makefile:MKMAIN_CMD    = mkmain.sh
    ./Makefile.in:MKMAIN_CMD    = mkmain.sh
    ./ChangeLog:    * Makefile.in, win32/Makefile.sub (RUNCMD, MKMAIN_CMD):
    macros to
    ./win32/Makefile.sub:MKMAIN_CMD    = mkmain.bat
    ./uncommon.mk:  @$(RUNCMD) $(MKMAIN_CMD) MAKE=$(MAKE)
    ./uncommon.mk:exts: $(MKMAIN_CMD)
    ./uncommon.mk:$(MKMAIN_CMD): $(MKFILES) incs $(PREP) $(RBCONFIG) $(LIBRUBY) 
    ./common.mk:    @$(RUNCMD) $(MKMAIN_CMD) MAKE=$(MAKE)
    ./common.mk:exts: $(MKMAIN_CMD)
    ./common.mk:$(MKMAIN_CMD): $(MKFILES) incs $(PREP) $(RBCONFIG) $(LIBRUBY) 

but nothing that seems to generate said file that I can tell.
