[R-SIG-Mac] RSPerl on OS X Server 10.4.11

I'm having some trouble getting RSPerl working on an XServe cluster.  Using:

perl v5.8.6
R v2.6.2 (installed from binaries from CRAN)
RSPerl v0.92-1
OS X Server 10.4.11, PowerPC G5

I'm installing with:

R CMD INSTALL -c -l '/home/gdowns/R' --configure-args='--with-in-perl'  

and I'm getting:

> library("RSPerl")
Error in dyn.load(file, ...) :
   unable to load shared library '/home/gdowns/R/RSPerl/libs/ppc/RSPerl.so':
   dlopen(/home/gdowns/R/RSPerl/libs/ppc/RSPerl.so, 6): Symbol not  
found: _boot_R
   Referenced from: /home/gdowns/R/RSPerl/libs/ppc/RSPerl.so
   Expected in: dynamic lookup

Error: package/namespace load failed for 'RSPerl'

I tried building R from scratch, using:

./configure --prefix=/tmp/R/ --enable-R-shlib

(then repeated the install of RSPerl with this special version of R)

RSPerl *does* work with this version of R.  I'm confused because  
question 1.3 of the RMacOSX-FAQ says:

"Note that the CRAN binary includes R shared library, so there is no  
need to re-compile R with --enable-R-shlib. "

I also note that when installing RSPerl with the binary distribution  
of R, the R CMD INSTALL process does not generate the perl modules (in  
the RSPerl/perl directory).

I'm not sure where I'm going wrong with this.  I'd highly prefer to  
stick with the pre-compiled binary to make upgrading easier.  Plus I'm  
sure that the version I built today is not as well optimized as the  
binary distribution!

If I really do need to compile R from scratch, can anyone recommend  
the appropriate configure flags?

many thanks and best regards,
