Trying to compile "R" from source.

[Andre Mikulec]

All,

I am trying to compile "R" from source.

I am stuck.  I am getting an error. Please, help.

My configure line:
https://github.com/AndreMikulec/r-build/blob/99bec605560b6b07de8847b481157d3320515b44/build_script.sh#L513
```
./configure --disable-rpath --enable-R-shlib --enable-BLAS-shlib=no --enable-java=no --without-readline --with-blas --with-lapack --without-x --prefix=${rroot}
```

My error lines:
https://ci.appveyor.com/project/AndreMikulec/r-build/builds/39440541#L1470
```
checking whether zlib support suffices... yes
checking for BZ2_bzlibVersion in -lbz2... no
checking whether bzip2 support suffices... configure: error: bzip2 library and headers are require
```

Thanks,
Andre
