lp_solve installing problem

[Deeparnab Chakrabarty]

I am getting the following error while trying to install lp_solve

~ $sudo port install -d lp_solve
--->  Computing dependencies for lp_solve
--->  Staging lp_solve into destroot
Error: Target org.macports.destroot returned: xinstall: Unable to chdir to
/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_math_lp_solve/work/lp_solve_5.5/lpsolve55/bin/osx64,
No such file or directory
Error: Status 1 encountered during processing.
Before reporting a bug, first run the command again with the -d flag to get
complete output.

Help?
