Unable to find file ... cgen-opc.scm

[Joern Rennecke]

My workstation was upgraded from Red Hat eEnterprise Linux 3 to
Red Hat Enterprise Linux 5.1, and now my cgen rebuilds fail.

After changing the cpu file, I always to a full rebuild, i.e.:
cd ..;rm -rf bld-arc;mkdir bld-arc;cd bld-arc;../src/configure  --target=arc-elf --enable-cgen-maint --with-guile=/usr;make all-sim CFLAGS=-g

That worked fine before the upgrade.  However, now I get:

...

Is there something wrong with the guile 1.8 that comes with RHEL 5, or
do I need to apply some patch to cgen?

This one is new to me.  Does strace identify the attempted open?
Does this happen with absolute configure-$srcdir?

I have seen these kind of issues with cgen when using relative paths.
cgen (or guile) seems to prefer paths be absolute where possible, e.g.
CPUDIR.
