Macros need to be at the beginning of logical input lines.

That is expected because ".PSPIC" is not a macro but plain text
in your example.

The following minimal example works for me:

   $ cat tmp.roff                                                 
  initial text
  allbox tab(@);
  l lw(2i) l.
  .PSPIC -L build/gnu.eps
  final text

   $ groff -t tmp.roff >
   $ gv

   $ man 7 tbl
  In place of any data cell, a text block can be used.  It starts with T{
  at the end of a physical input line.  Input line breaks inside the text
  block neither end the text block nor its data cell.  It only ends if T}
  occurs at the beginning of a physical input line and is followed by an
  end-of-cell indicator. 

   $ man 1 tbl
  A text block can be used to enter data as a single entry which would be
  too long as a simple string between tabs.  It is started with 'T{' and
  closed with 'T}'.  The former must end a line, and the latter must
  start a line, probably followed by other data columns (separated with
  tabs or the character given with the tab global option).
