Check your shell with echo $SHELL - getting the command not found error is usually from running export DISPLAY in a csh/tcsh shell. It's not a valid command.
If you are using ksh or sh, you might need to run the DISPLAY and export separately.
$ DISPLAY=servera:0 ; export DISPLAY
You might also need to use the xhost serverB command on serverA - it tells serverA to accept the display from serverB.
Look at the man pages for export and xhost. It may also help if you post your OS and version of both servers.

pvm_unexport
EXPORT(3PVM) EXPORT(3PVM)
NAME
pvm_export, pvm_unexport - Mark environment variables to export through spawn
SYNOPSIS
C int cc = pvm_export( char *name )
int cc = pvm_unexport( char *name )
Fortran Not available
PARAMETERS
name Name of an environment variable to add to or delete from export list.
DESCRIPTION
The routines pvm_export and pvm_unexport are provided for convenience in editing environment variable PVM_EXPORT, while maintaining the
colon-separated list syntax it requires. The variable can be modified by other means, and at the same time by the pvm_export functions.
pvm_export checks to see if a name is already in PVM_EXPORT before including it, and exporting a name more than once is not considered an
error. Likewise, pvm_unexport will not complain if you specify a name not in PVM_EXPORT.
EXAMPLES
C:
/* PVM_EXPORT=SHELL:HOME */
pvm_export("DISPLAY");
pvm_export("TERM");
pvm_unexport("HOME");
/* PVM_EXPORT=SHELL:DISPLAY:TERM */
ERRORS
No error conditions are currently returned by pvm_export and pvm_unexport.
