I am attempting to compile R v1.6.1 on my SGI Octane (running IRIX 6.5)
and ran into the following error when I encountered the new recommended
package _mgcv_ (using make)

----------

     R_LIBS= ../../../bin/R CMD INSTALL -l ../../../library mgcv.tgz
* Installing *source* package 'mgcv' ...
** libs
gcc -I/usr/local/R-1.6.1/include -I/usr/freeware/include -g -O2 -c gcv.c
 -o gcv.o

  matrix.c -o matrix.o

gmake: *** [matrix.o] Error 1
ERROR: compilation failed for package 'mgcv'
*** Error code 5 (bu21)
*** Error code 1 (bu21) (ignored)

----------

Upon eliminating this package, all subsequent "Recommended" packages
installed just fine.  Any ideas on what went wrong?
