I hope   the FindR.cmake script  I am using   'finds'  all the relevant 
R-executable programs.  Here is a snippet of the script I use:


     FIND_PROGRAM(R_EXE_FILE              R              ${PATH})    
     FIND_PROGRAM(R_Rscript_EXE_FILE      Rscript        ${PATH})  
     FIND_PROGRAM(R_bin_EXE_FILE          exec/R         ${PATH})   


As regards   'error-traps'.   Here are the two traps at the top of the 
script:-

FIND_PROGRAM(R_bin_EXE_FILE           exec/R     ${PATH} )  
IF(R_bin_EXE_FILE-NOTFOUND)
	MESSAGE(STATUS "Could NOT find R ")
ENDIF(R_bin_EXE_FILE-NOTFOUND)

IF(NOT R_bin_EXE_FILE)
	MESSAGE(STATUS "Could NOT find R ")
ENDIF(NOT R_bin_EXE_FILE)


I hope I ensured R is found correctly (at the bottom of the script) like  
this:-

   IF(R_HOME  AND R_EXE_FILE AND  R_bin_EXE_FILE AND R_SHARED_LIB  AND 
R_LIBS_REQ  AND  R_EXTRALIBS_REQ  AND  R_HEADER_FILE )
       SET(R_FOUND  TRUE )
       MESSAGE(STATUS  "Found R: ${R_HOME}: libs: ${R_LIBS_REQ} and 
${R_EXTRALIBS_REQ}" )
   ENDIF(R_HOME  AND R_EXE_FILE AND  R_bin_EXE_FILE AND R_SHARED_LIB  AND 
R_LIBS_REQ  AND R_EXTRALIBS_REQ  AND  R_HEADER_FILE )


with the above included, a snippet from  running cmake  gives:-

however 'make' still fails at 79%


Now as I said in my last posting  there are two ~/bin directories for R:-
poet [ ~ ]$ ls /usr/local/R-2.10.1/bin
R  Rscript
poet [ ~ ]$
poet [ ~ ]$
poet [ ~ ]$ ls /usr/local/R-2.10.1/lib64/R/bin
BATCH    INSTALL  R       Rcmd    Rdconv  Rprof    SHLIB  Stangle  build  
config  f77_f2c     libtool        pager
COMPILE  LINK     REMOVE  Rd2dvi  Rdiff   Rscript  Sd2Rd  Sweave   check  exec    
javareconf  mkinstalldirs  rtags
poet [ ~ ]$
poet [ ~ ]$
(exec is a directory containing the R binary ~7Mbytes in size)


If I am targeting the wrong R's  ( or indeed the right ones) I would be 
grateful if someone on list could let me know.

yours sincerely
