Problem with LaTeX invoices.

[TSS Support]

Using a default install of 1.5.0pre5 for a new project, on Debian Sarge. I 
have the tetex-bin package installed, so pslatex is there. However, I am 
getting the following error every few minutes per invoice:

 failed: pslatex 
/usr/local/etc/freeside/cache.DBI:Pg:dbname=freeside/invoice.2.0OtXDXVf.tex 
failed: Inappropriate ioctl for device at 
/usr/local/share/perl/5.8.4/FS/cust_bill.pm line 1164. Stack: 
[/usr/local/share/perl/5.8.4/FS/cust_bill.pm:1164] 
[/usr/local/share/perl/5.8.4/FS/cust_bill.pm:361] [(eval 1098):1] 
[/var/www/freeside/misc/bill.cgi:19] [/var/www/freeside/autohandler:1]

I can run pslatex okay from the command line. Looking in cust_bill.pm at the 
appropriate line doesn't seem that enlightening. Anyone run into this one 
before? Rooting around the documentation didn't seem to turn up anything. I 
know this feature is new, so perhaps it's best to leave it out for now - our 
successful Freeside on another server is still using text billing for that 
reason.

Thanks,
