R help - Oct 2011 - Unable to load local library via GUI

Hi all,

Not sure if this is the best list, please point me to a more appropriate list if
necessary.

Running Mac OSX 10.7.1
R version 2.13.1 Patched (2011-08-14 r56741)
Copyright (C) 2011 The R Foundation for Statistical Computing
ISBN 3-900051-07-0
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)

I have a locally developed library (libmlalgs), which I am able to install via
the command line:
sudo R CMD INSTALL libmlalgs
In the /Library/Frameworks/R.framework/Versions/2.13/Resources/library/libmlalgs
there is a .so file
/Library/Frameworks/R.framework/Versions/2.13/Resources/library/libmlalgs/libs/x86_64/libmlalgs.so

This runs and installs OK.
I am able to run R64 in the command line and load the libmlalgs library fine :)
I am able to use Rstudio and load the libmlalgs library fine.

However, when using the R64.app and try and load the library within the GUI I am
getting the following error:
Error in dyn.load(file, DLLpath = DLLpath, ...) : 
  unable to load shared object
'/Library/Frameworks/R.framework/Versions/2.13/Resources/library/libmlalgs/libs/x86_64/libmlalgs.so':
 
dlopen(/Library/Frameworks/R.framework/Versions/2.13/Resources/library/libmlalgs/libs/x86_64/libmlalgs.so,
6): Library not loaded: libRblas.dylib
  Referenced from:
/Library/Frameworks/R.framework/Versions/2.13/Resources/library/libmlalgs/libs/x86_64/libmlalgs.so
  Reason: image not found
Error in library(libmlalgs) : .First.lib failed for 'libmlalgs'

I know the libmlalgs.so is in the right place and the permissions look OK:
-rwxr-xr-x  1 root  admin  58384  3 Oct 14:30 libmlalgs.so

So I am stumped as to why the GUI is unable to read the file.

Any pointers would very welcome. As I am a textmate user and it passes the code
to the R64.app, I currently stuck with either command line or Rstudio (it's
nice but is currently missing some key features textmate has)


Many thanks,
Noel Faux

  I'm not sure of the answer, but there has been a lot of discussion
of similar issues (showing up as problems loading libRblas.dylib) on
the R-sig-mac [r-sig-mac at r-project.org] mailing list.  I would search
through the archives there and then ask on that list if you can't find
a suitable answer.
