Thanks for the information that you are using csh.  I think that is the source
of the confusion.  Our installation documentation is written assuming use of a
POSIX standard shell, such as sh, bash, ksh, or zsh.  The csh shell has 
different
syntax for setting environment variables, requiring use of 

  setenv ENV_VAR value

instead of

  export ENV_VAR=value

or just

  ENV_VAR=value

So where the instructions say

  export LD_LIBRARY_PATH={DIR1}/lib:$LD_LIBRARY_PATH

you would instead use

  setenv LD_LIBRARY_PATH "{DIR1}/lib:$LD_LIBRARY_PATH"

and instead of

  CPPFLAGS=-I{DIR1}/include LDFLAGS=-L{DIR1}/lib ./configure --prefix={DIR1}

you would use

  setenv CPPFLAGS "-I{DIR1}/include"
  setenv LDFLAGS  "-L{DIR1}/lib"
  ./configure --prefix={DIR1}

For all these examples, you would use

  /hou_proj2/EM_projects/xyu/Ov2-deps

instead of

  {DIR1}

I'm sorry the documentation doesn't make clear that a standard POSIX
shell is assumed.  I will correct that omission.

There was also a mistake on that page that had an incorrect "-L" in the command

  export LD_LIBRARY_PATH=-L{DIR1}/lib:$LD_LIBRARY_PATH

which should have been just

  export LD_LIBRARY_PATH={DIR1}/lib:$LD_LIBRARY_PATH

That has also been corrected.
