Couldn't detect type of database

I recently lost a hard drive and after successfully restoring 
everything, I think, I'm getting "Error opening database `current.1': 
DatabaseOpeningError: Couldn't detect type of database"

The directory current.1 contains the following files:

-rw-rw-r-- 1 jwl jwl  30064640 Aug 28 23:44 docdata.glass
-rw-rw-r-- 1 jwl jwl       151 Aug 28 23:44 iamglass
-rw-rw-r-- 1 jwl jwl 767115264 Aug 28 23:44 position.glass
-rw-rw-r-- 1 jwl jwl 383213568 Aug 28 23:44 postlist.glass
-rw-rw-r-- 1 jwl jwl 203341824 Aug 28 23:44 termlist.glass
-rw-rw-r-- 1 jwl jwl         0 Aug 28 23:44 flintlock

I know that I was using 1.4.1 before, so I reinstalled that version and 
now delve decided that the db was OK, however when I went to install 
Xapia./XS/WritableDatabase.xs:30:47: error: missing binary operator 
before token "("
  #if defined XAPIAN_AT_LEAST && XAPIAN_AT_LEAST(1,5,0)
                                                ^
./XS/QueryParser.xs:54:47: error: missing binary operator before token "("
  #if defined XAPIAN_AT_LEAST && XAPIAN_AT_LEAST(1,5,0)
n::Search from cpan, it gave me errors.

I guess I'll have to upgrade the db to work with a newer version of 
Xapian somehow.  Is that possible?

Thanks,

Jim.
