1. I try to execute ADTEx(http://adtex.sourceforge.net/)

Our linux was installed R3.1.

Is it possible to use this type of R in DNAcopy?

2. And of process to install R2.15, I get a  message '

/usr/bin/ld.bfd.real: /usr/local/lib/libz.a(crc32.o): relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/libz.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make[1]: *** [R_X11.so] Error 1
make[1]: Leaving directory `/home/jhleelab/R-2.15.3/src/modules/X11'
make: *** [R] Error 2

Because of 2. problem, I want to use R3.1 in installing or executing of DNAcopy.

show me the way to solve these problem,.

 Help me?
