Package Matrix does not compile in R-devel_2009-01-10

Dear developers,

today I tried to build and install R-devel_2009-01-10 on FreeBSD 
8.0-CURRENT (i386) for testing purposes.

All went well until compiling the now recommended (integrated) Matrix 
package. At this point the following break occured:

------------------------------------------------

------------------------------------------------


Please note, that on FreeBSD there is a BSD 'make' as default. If I want 
to use gmake instead, I explicitly have to set it. Unfortunately this 
does not work within building the whole R-devel system.

With R-2.8.1 I have no problems installing and using R. When I want to 
build the (external) Matrix package I have to set an environment 
variable to gmake, found at /usr/local/bin/gmake and all works well.


Now my question: Is it possible to change the configure/build of the 
integrated Matrix package on R-devel? For all other packages there is no 
need to do so (at least for FreeBSD ;-)

Please let me know if I can help.

Thanks in advance,
Rainer Hurling
