You are presumably (you have not told us) running Linux and do not have 
g77 installed (so I guess you installed R from an RPM or similar).  The 
best solution is to install it.  On my system

gannet% rpm -ql gcc-g77-3.4.2-6.fc3
/usr/bin/f77
/usr/bin/g77
/usr/lib/gcc
/usr/lib/gcc/i386-redhat-linux
/usr/lib/gcc/i386-redhat-linux/3.4.2
/usr/lib/gcc/i386-redhat-linux/3.4.2/include
/usr/lib/gcc/i386-redhat-linux/3.4.2/include/g2c.h
/usr/lib/gcc/i386-redhat-linux/3.4.2/libfrtbegin.a
/usr/lib/gcc/i386-redhat-linux/3.4.2/libg2c.a
/usr/lib/gcc/i386-redhat-linux/3.4.2/libg2c.so
...

The next best is to edit R_HOME/etc/Makeconf and remove -lftrbegin from 
FLIBS.
