Can't install vt on cluster

[boutrys]

hello,

I tried

#this will create a directory named vt in the directory you cloned the repository

1. git clone https://github.com/atks/vt.git

#change directory to vt
2. cd vt

#update submodules
3. git submodule update --init --recursive

#run make, note that compilers need to support the c++0x standard
4. make

#you can test the build
5. make test

But at step 4
configure: error: zlib development files not found

HTSlib uses compression routines from the zlib library http://zlib.net.
Building HTSlib requires zlib development files to be installed on the build
machine; you may need to ensure a package such as zlib1g-dev (on Debian or
Ubuntu Linux) or zlib-devel (on RPM-based Linux distributions or Cygwin)
is installed.

FAILED. This error must be resolved in order to build HTSlib successfully.
make[1]: Entering directory '/work/gr-fe/sboutry/tools/vt/lib/htslib'
config.mk:2: *** Resolve configure error first. Stop.
make[1]: Leaving directory '/work/gr-fe/sboutry/tools/vt/lib/htslib'
make: *** [Makefile:154: lib/htslib/libhts.a] Error 1

I installed zlib but didnt change the error

Anyone know how to fix this ?

Thanks in advance

Simon
