Are you sure you tried a Perl script, the following seems to work (Tested on Solaris 5.10 sparc with Perl-5.8.4)
Code:
skrynesaver@busybox ~/tmp$ perl -w -Mstrict -e 'open my $long , ">" , "longLines.txt"; for (0..30000){print $long "<record><field1>data</field1><field2>other data </field2></record>";}'
skrynesaver@busybox ~/tmp$ wc  longLines.txt
      0   60003 1980066 longLines.txt
skrynesaver@busybox ~/tmp$ perl -w -Mstrict -e 'open(my $long, "<", "longLines.txt") || die "Could not open longLines.txt $!\n";my $data=readline($long);close $long;$data=~s/<record>/\n<record>/g;open my $short, ">", "shortLines";print $short $data;close $short'
skrynesaver@busybox ~/tmp$  wc  shortLines
  30001   90003 2010067 shortLines

perldgux

PERLDGUX(1)						 Perl Programmers Reference Guide					       PERLDGUX(1)

NAME

       perldgux - Perl under DG/UX.

SYNOPSIS

       One can read this document in the following formats:

	       man perldgux
	       view perl perldgux
	       explorer perldgux.html
	       info perldgux

       to list some (not all may be available simultaneously), or it may be read as is: as README.dgux.

DESCRIPTION

       Perl 5.7/8.x for DG/UX ix86 R4.20MU0x

BUILDING PERL ON DG
/UX
   Non-threaded Perl on DG/UX
       Just run ./Configure script from the top directory.  Then give "make" to compile.

   Threaded Perl on DG/UX
       If you are using as compiler GCC-2.95.x rev(DG/UX) an easy solution for configuring perl in your DG/UX machine is to run the command:

       ./Configure -Dusethreads -Duseithreads -Dusedevel -des

       This will automatically accept all the defaults and in particular /usr/local/ as installation directory.  Note that GCC-2.95.x rev(DG/UX)
       knows the switch -pthread which allows it to link correctly DG/UX's -lthread library.

       If you want to change the installation directory or have a standard DG/UX with C compiler GCC-2.7.2.x then you have no choice than to do an
       interactive build by issuing the command:

       ./Configure -Dusethreads -Duseithreads

       In particular with GCC-2.7.2.x accept all the defaults and *watch* out for the message:

	   Any additional ld flags (NOT including libraries)? [ -pthread]

       Instead of -pthread put here -lthread. CGCC-2.7.2.x that comes with the DG/UX OS does NOT know the -pthread switch. So your build will fail
       if you choose the defaults.  After configuration is done correctly give "make" to compile.

   Testing Perl on DG/UX
       Issuing a "make test" will run all the tests.  If the test lib/ftmp-security gives you as a result something like

	   lib/ftmp-security....File::Temp::_gettemp:
	   Parent directory (/tmp/) is not safe (sticky bit not set
	   when world writable?) at lib/ftmp-security.t line 100

       don't panic and just set the sticky bit in your /tmp directory by doing the following as root:

       cd / chmod +t /tmp (=set the sticky bit to /tmp).

       Then rerun the tests. This time all must be OK.

   Installing the built perl on DG/UX
       Run the command "make install"
